Re: Most powerful reinforcement per faction

Republic: everyone except wookie warrior, commando's tankiness probably beats arcs extra dps, but they're all top tier.

Separatists: tie between aerial and b2 super, droideka can be really good but is very, very situational

Rebellion: aerial

Empire: tie between death trooper and aerial

Resistence: tie between aerial and spy

First Order: aerial is a bit better, but sith trooper still rocks and is a bit better in cqc
