Raynor is a commander very oriented to the use of the infantry, the firepower of his bioball is very oriented to the units that he chooses to integrate it, marines to counter flying units and to spend the excess of minerals quickly, marauders to counter armored units and firebats to counter light units. Of requiring extra firepower has access to its calldowns and mechanical units. These can even occupy a more main role or displace bioball in special situations.
Power Set 1:
- The stimpack duration although it is an insignificant advantage in early game due to the low cost of the stimpack, its cost in health will begin to notice in later stages of the game, reason why not having to activate the stimpack so often will allow medics need less energy to heal infantry units.
- The Speed Increase for Drop-Pod units, on the other hand, affects all units and calldowns, being particularly useful for aggressive players who are constantly replenishing units during combat; Unfortunately only lasts 30 sec so this advantage between combat is lost, also the units dropped when do put many points in this option tend to lead the attacks being also the most vulnerable to die.
Power Set 2:
- The Reduced cooldown for Hyperion will allow you to use Hyperion more often, being very useful to assault enemy bases, however, because of the value of this calldown, probably do not want to waste it, if do tend to keep this calldown reserved for a long time, would be wasting points that could be used with the Reduced cooldown for Banshee Airstrike
- The Reduced cooldown for Banshee Airstrike will allow greater use of dusk wings, allowing to gain greater dps in multiple combats (due to their lower cooldown, they can be used in a more liberal way, besides that these units together have a greater dps than Hyperion), but remember that if do tend to keep this calldown reserved for a long time, you would be wasting points that could be used with the Reduced cooldown for Hyperion
Power Set 3:
- That Medic heal another target allows to recover better of the battles so it will require less energy and medics to attend a bioball allowing to have more units of combat, in addition that will help to face better splash damage of attacks and casters in area.
- Reduced damage when healed by medic will increase the life expectancy of your units in the middle of a combat, in the early game this can be appreciated as Raynor will not be able to recover from considerable losses easily and as the game progress increases Its performance against units that hit hard and that resist enough, also allows to some extent to better face the splash damage (Better even if this is combined with the heal splash)
Raynor's has the ability to call down the Hyperion briefly to the battlefield, with various combat capabilities, including the Yamato cannon which can eliminate groups of enemies with high HP quickly, Point-defense drones that protect Raynor's army, an aura that increases the damage of allied units, and the ability to teleport to any location on the battlefield, wreaking havoc on enemy lines. Summoning and warping the Hyperion does not require line of sight of the location, allowing the player to reach distant objectives before overcoming the enemy forces. Its long range batteries enables you to eliminate dangerous threats to Raynor's infantry before they get within striking distance, such as siege tanks, while the area-of-effect Yamato cannon deals substantial damage to units with large health pools or massed units. PDDs should be used to cover as much area as possible to defend both the Hyperion and surrounding units. The support passive ability of the Hyperion also allows it to buff nearby units, and works well with massed infantry.
Raynor's secondary calldown is the Dusk Wings, a group of banshees that start cloaked on the field and will attack nearby ground units. This has a faster cooldown than the Hyperion, and can be used for precision strikes at key targets as well as add extra damage to a push. Upon initially being summoned, they will strafe the area under them, useful for dealing damage to concentrated light units. However, their cloaking fields are not permanent, and can be deactivated before the Dusk Wings despawn to either to draw the enemy's attention or to save their energy until detectors have been removed. As the Dusk Wings despawn, they will have a moment of invulnerability as they fly off the map, but they will still be able to attack while the animation plays out.
Remember that these calldowns benefit from attack upgrades (thus avoiding the loss of DPS by increase of armor of enemy units as the game progresses), armor upgrades (including the health bonus), and range upgrades from the armory.
Raynor focuses primarily on infantry units in his army, with support deriving from factory and starport units. Marines, marauders and medics are a classic pairing, Although marines possess good DPS and can attack both ground and air units, they are vulnerable to anti-light compositions. Meanwhile, marauders are strong against armored units and have more than twice the HP than marines (which makes them less vulnerable to splash damage) but are vulnerable to air attacks and anti-armored units. Using marines and marauders together allows them to cover their weaknesses and maintain their strengths. Firebats can be very useful for killing large groups of light enemy of enemy waves (such as zerglings and zealots) as well as serving as a meat shield for bioball (their range makes them tend to lead attacks but not away from bioball), but the core damage of the infantry army should come from the marines. Once upgraded, medics can heal all allied units, biological and mechanical alike. Siege tanks provide siege support in defensive missions, serving as an alternative to the effective but high-maintenance spider mines of the vultures.
Raynor's bunkers supported with SCVs are a great way to deal with early attack waves, and a single fully loaded bunker with level upgrades can hold off the initial attack waves while Raynor and his ally build up their forces for a push out. Stimpacks can be used inside bunkers even if units are below the usual minimum health required, allowing for the player to have extra damage when enemy attack waves bear down.
Among Raynor's aerial units are the vikings, the banshees and the battlecruisers; his vikings are relatively inexpensive units that when properly amassed and upgraded can be some of the most powerful air units in the game, capable of inflicting a large amount of damage in area, with a large enough range to attack from behind while other units tank the frontlines. Vikings can travel long distances considerably fast for brief moments. Raynor's banshees are effective when having to counter enemy waves with a large number of ground units, and their cloak allows them to deal out heavy damage to priority targets without fear of retribution. Raynor's battlecruisers also pack a hefty punch, but can be expensive and slow to produce.
Raynor can build combat units 50% faster than average, and his orbital drop allows him to reinforce anywhere on the map instantly. A good strategy is to just create a massive army of infantry units with support units aiding the push. Aside from the occasional air threat, there is not much the biological army cannot handle. However, Raynor's army can be ground down, as such units should be reinforced and rally points should be set on top of the army. Some missions will necessitate getting higher-tier air units, however, especially if the enemy fields splash damage units (lurkers, reavers, disruptors, banelings, ultralisks, siege tanks, etc.) which can annihilate infantry units. Enemy high templars and infestors can also cause Raynor's infantry a lot of grief, and should be focused down by support units or by Raynor's calldowns. Because Raynor's core bio army is ranged and heavily mobile, it is easy for Raynor to kite enemy forces from out of defensive positions, allowing Raynor to engage them without them being supported by static defense. This allows for smaller engagements with fewer casualties.
One of the most powerful units in Raynor's arsenal, particularly on maps with set defensive lanes such as "Mist Opportunities" and "Temple of the Past" is his vultures. Upgraded spider mines are powerful, recharge quickly, and can instantly wipe out most ground based attack waves. Stack them in small choke points, and the enemy will be unable to clear them before the mines are able to quickly destroy their hybrid behemoths. In defensive missions this tactic can be expensive so it is advisable to have enough extra orbital command to maintain demand. Vikings and other anti-air units should also be deployed to aid the vultures to help cover from air units the enemy may bring.
Having multiple orbital command centers will not only give Raynor a strong influx of minerals, but also give him the ability to use multiple scans whenever cloaked units attack, give sight of enemy bases or raised zones before a push, also allowing the allied player to use calldowns preemptively on previously hidden areas. Because of his MULEs, Raynor has the ability to churn out a marines and lower gas cost units with ease, so a large number of orbital commands should be met with an equally large number of factories. MULEs can also be used in situations where a unit is needed to hold a point (like "Lock & Load" or "Chain of Ascension") or to repair allied units if the medics are not close by.
Command centers and orbital commands have the ability to lift off and move, allowing them to be built in before clearing an expansion of rocks or enemy fortifications and be placed on the expansion after the area is safe. Since much of Raynor's biological units cost only minerals, building refineries can be delayed in favor of constructing orbital commands and an initial army of marines and vultures. Alternately, Raynor can take only the essential geysers needed for units like medics and upgrades for his core units, and give the geysers at his expansions to more gas heavy allies like Nova and Vorazun.
Artanis is an excellent teammate for Raynor. Artanis's Guardian Shell and Shield Overcharge greatly extends the lifespan of Raynor's fragile infantry units, especially against enemy AoE attacks. Artanis' immortals can deal with heavy hybrid behemoths, thus compensating for Raynor's general lack of durable units. Raynor's marines provide superior anti-air capabilities over Artanis's dragoons. Medics can extend the lifespan of zealots (which tend to die rapidly otherwise) and other units of combat, while SCVs and MULEs can repair Artanis's mechanical units while they are idle, and bring units that have triggered their guardian shells back to full health.
Karax is a questionable teammate for Raynor. With the exception of powerful battlecruisers, Raynor's Rapid Recruitment talent creates redundancy with Chrono Field, but if combined with Chrono Wave, Raynor can replenish full armies almost instantly. Unity Barrier can make Raynor's infantry slightly more durable. Karax's superior automated defenses allows Raynor to forgo bunkers. Reconstruction Beam may not affect Raynor's infantry, but it can help his mechanized units and bunkers, the latter of which normally have survivability issues at higher difficulties. Its defenses can be redundant with the spider mines in most of the maps (one tends to overshadow the other depending on the situation), since Raynor once has its developed economy can arm a great army and defend itself with spider mines, Karax can opt for reducing the amount of defenses on offensive maps and arm an army that can also be supported by the medics with extra healing and reduction of damage. Vikings and marines compensates for Karax's weak anti-air capabilities. Additionally scan can combine well with solar flare and orbital assaults, allowing the elimination of enemy waves from a distance.
Vorazun is a questionable teammate for Raynor. Vorazun is fully capable of annihilating even the toughest enemy forces on its own. Corsairs can be very useful to Raynor by disabling the attacks of dangerous waves or fortified bases, so that he can attack without fear of reprisals. Raynor's scanner sweeps are invaluable towards her detection issues; Vorazun's oracles have a higher tendency to die than observers. Emergency Recall can be useful to Raynor if Vorazun uses her Dark Pylon smartly, saving his fragile infantry from death. Lastly, Raynor's marines are generally better at anti-air than Vorazun's stalkers, so he can cover against air attacks in her stead while she focuses more on ground forces, also can take advantage of the dark pylons to transport the troops quickly.
Alarak is an excellent teammate for Raynor. Raynor's large anti-air support infantry increase the effectiveness of Empower Me; Alarak's havocs to boost the attack range of marines. Coordinating their cooldowns allows Raynor to warp the Hyperion to any point on the map, at which point Alarak can immediately send in the Death Fleet to support it, and thereby teleport their armies to the Hyperion en masse. Alarak's wrathwalkers and ascendants can quickly focus down powerful enemy units that pose a threat to Raynor's fragile marines.
Fenix is a powerful teammate for Raynor, with Raynor covering for many of Fenix's weaknesses. Both armies are high damage but low health, but the addition of medics means Fenix' forces, which normally can't heal, become more hardy. This means frontline forces like legionaries, Kaldalis and Fenix' preator armor can soak more damage. In addition, Raynor's calldowns can help defend against enemy attacks and help in pushes, while Fenix's recall can also give Raynor's marines much needed mobility to push, take objectives or fall back.
Swann is a good teammate for Raynor. Both commander's armies can function perfectly well without the other; Swann's vespene gas production bonus is rarely an issue for Raynor's biorganic infantry, but it is very helpful if Raynor wants to field higher-tech units. Swann's superior automated turrets allows Raynor to forgo bunkers. Their true synergy lies with Swann's tech reactors being constructed for Raynor's buildings (either by converting the Raynor add-ons to Tech Reactors or by constructing them for him), allowing Raynor to double-produce higher-tier units like marauders, siege tanks, and battlecruisers. Raynor's mechanized units can also benefit from having Swann's science vessels to repair them, or have Swann's SCVs perform repairs without costing anything and vice versa with medics and their reduction of damage.
Nova can be a powerful teammate with Raynor. Raynor possesses the larger force, while Nova's more small tactical force can clear key targets. Air strike entrenched positions as Raynor pushes forward. In addition, medics, especially with the ability to heal mechanical units, augment their already powerful force Nova has and makes them even harder to kill during combat. Raynor going the vulture/spider mine build can focus their efforts on specific attack paths, as Nova's forces can take out most attack waves on their own.
Kerrigan is an excellent teammate for Raynor. Kerrigan benefits from medics' healing; her zerglings and ultralisks can lead charges while "meat shielding" for Raynor's infantry. Unfortunately, Raynor rarely benefits by Kerrigan's Assimilation Aura due to his MULEs and low gas requirements for infantry, and Orbital Drop Pods creates redundancy with Kerrigan's Omega Worms as a way of replenishing troops, but although it can still allow his troops to travel long distances quickly. Finally, Kerrigan's immobilizing wave will allow him to attack the enemy without fear of reprisals.
Zagara is a questionable teammate for Raynor. Zagara benefits from medics's healing, but it is generally redundant as her army tends to be suicidal. Zagara can destroy entrenched positions easily, and her aberrations and roaches can lead charges while "meat shielding" for Raynor's infantry. Both use units with high attack velocity (especially with Zagara's Mass Frenzy), so both armies benefit greatly from the Hyperion's +2 attack buff and the armor reduction debuff's zerglings , allowing them to inflict a lot of damage on little time. Zagara's Mass Frenzy can push Raynor's infantry to absurd speeds and attack rates when they also use stimpacks.
Abathur is an excellent teammate for Raynor. Abathur's mend ability can aid in large engagements when used alongside Raynor's medics. Raynor's marines can also cover Abathur's lack of early game anti-air. In mid-late game, Abathur's heavy units and high area of effect damage goes well with heavy infantry support from Raynor. Mend can also heal Raynor's infantry in huge numbers, saving his medics precious energy.
Stukov and Raynor have fairly minimal synergy. Both rely on large, more disposable armies, but Stukov can still screen for Raynor's infantry. Medics will often waste their energy on disposable infested, putting their further ahead and at risk during attacks. Both have high damage global abilities, but both have high cooldowns.
Prior to Patch 3.1.3, Raynor's initial talent Rapid Recruitment was named Infantry Specialist, and had different effects. Additionally, the Improved Stim ability was the standard Stimpack ability in terms of usage; it had to be researched, provides 50% boosts to movement and attack speed, and needed 10 HP to use. The Stabilizer Medpack upgrade also did reduce the 25% damage taken by units being healed; this passive behavior is called "Safeguard".
Prior to patch 3.3.0, Raynor’s level 8 upgrade, Orbital Drop Pods, did not applies to Starport units.
Prior to patch 3.3.2 Mastery: Medics heal a nearby additional target for X% of heal. Only increase 2% per level (Now is 3%)
Prior to patch 3.4.0, the bunkers only had 400 HP, to gain + 150HP and shrike turret needed to be investigated. Developer Comments: Bunkers are not getting a lot of use. They have some upgrades available but they don't help in the early game and have questionable value in terms of cost and time investment later on. Instead of unlocking research at level 7, Raynor will now be able to build upgraded Bunkers at level 7. The life bonus has also been increased slightly. Instead of Level 10 Armor upgrades in the Armory and Engineering Bay increased life in addition to increasing armor there was Level 10 Double Mule. Developer Comments: The double M.U.L.E. upgrade is currently encouraging a mass Orbital Command strategy which allows Raynor to make an endless stream of only Marines. Players not employing this strategy gain a fairly minor power increase. We decided to replace this upgrade with a powerful combat upgrade instead which should help Raynor against area damage and increase his overall survivability. This upgrade also effects all unit types including mechanical, so it should also help to make Factory and Starport units viable, rather than just allowing Raynor to simply make more Marines. In addition, the bonus of speed of attack of Level 15 only affected to the infantry units and there was not a clarification on the masters that affected the calldowns. Developer Comments: We also want to change this upgrade to affect all units including mechanical, again to open up Raynor's strategic options. While Raynor's core strength is his biological army, it was important to us not to discourage the use of the other units. We want to supplement his army with the right tools depending on the situation, and we were sending the wrong message by having this upgrade affect only his Barracks units.
Prior to patch 3.6.0, the battlecruisers had a energy bar, their skills had no cooldown and only had 450 HP. Developer Comments: Battlecruisers have increased life and no longer have energy. Yamato Cannon is now a cooldown based ability and can be used more often.
Prior to patch 3.7.0, the Medic's Stabilizer Medpacks upgrade only allowed medics to heal faster. Developer Comments: We're changing this upgrade to enable Medics to target Mechanical units. We're continuing to look at how Raynor can both be a better partner as well as open up additional army compositions. This also makes his Medic mastery bonuses viable for players who choose to go heavy mech.
