Star Wars: The Old Republic mirrors their classes across faction to keep PVP balance in check. The mirror class of the Mercenary is the Republic’s Commando. Like the Merc, the Commando likes to shoot things and blow them up... and he does it really, really well. In this player guide we’ll go over the two of the best skill trees and what sorts of abilities you’ll want to use out on the PVE battlefield. Our full PVP guide for the class will be coming at a later date. Maybe from YOU!
The Commando is an advanced class of the Trooper. Its skill trees are Combat Medic, Gunnery and Assault Specialist. The Assault Specialist tree is shared with the Vanguard. The Commando is the mirror class of the Mercenary. Combat Medic is a healing spec that uses kolto gas. Gunnery is a DPS tree that uses explosive to damage enemies and lower their armor. Assault Specialist is a tree that focuses on better management of Energy Cells and self preservation.
Playing a Combat Medic
Combat Medic is a pretty straightfoward healing spec. Advanced Medical Probe, Medical Probe and Hammer Shot will be your main heals. Hammer Shot heals if used on friendly targets if you have Combat Support Cell active. As an instant heal that uses no energy, it can be spammed but the amount healed is very low. Advanced Medical Probe has a cast time, costs 2 energy cells and is on a 12 second cooldown and if talented will reduce the energy used by your next Medical Probe. Medical Probe is a weaker version of Healing Scan without a cooldown, but costs 3 energy cells unless used after an Avanced Medical Probe. Medical Probe will also generate three extra charges of Combat Support Cylinder if talented. Field Aid removes debuffs, Trauma Probe allows your tank to get hit harder without dying as fast through its damage absorption, Kolto Bomb lets you heal 3 targets at once while increasing the healing they receive by 10% if talented and Bacta Infusion is a instant heal for emergency situations.
Playing a Gunnery
The Gunnery spec is all about reacting to procs and layering debuffs. Full Auto is your most powerful attack with talents nearly doubling its power, and attacks causing the cooldown to finish much earlier than it would alone. Grav Round is your main attack, adding gravity vortexes to the target, lower its armor and causing your next High Impact Bolt to do more damage. Demolition Round also does a large amount of damage but is not prioritized as high as using Full Auto. It's advantage is that it is an instant attack. If everything else is on cooldown, and you have all 5 stacks of Gravity Vortex built, throwing in a High Impact Bolt won’t hurt your damage. Hammer Shot is your filler shot when your energy is too low. Using any skill is better than using no skill, but if you can manage, every skill is better than Hammer Shot.
Playing an Assault Specialist
The Assault Specialist is a very CC focused spec with lots of DOTs. Much like the Pyrotech of the Mercenary (Empire Mirror Class), for PvE rotation Incendiary Round should be your first attack used and used again just before its dot runs out to keep the burning effect up. Besides that High Impact bolt will be your strongest attack, ignoring 30% of your targets armor, recharging energy after use and refreshing Plasma Cell's burn effect if active. Using Full Auto as it cools down and Charged Bolt as a filler will reset the cooldown of High Impact Bolt and make it free. On those occasions where you need energy cells, use Recharge Cells to give it a boost. Luckily the Assault Specialist spec gets 30 seconds off the cooldown of Recharge Cells too. Like the Pyrotech on the Empire, this isn’t the most easily used spec in the bunch, but it definitely has it’s uses (namely CC and DOT).
