I'm not sure I read this right. Are you saying that Powertechs are on the bottom tier for dps?
I think he means mercs, however dmg is not the merc's problem, their problem is how easy it is to shut down their rotation. Everyone can literally take turns interrupting a commando and throw in a few giggle emotes while they kill em. Imo, they need to either make tracer missile activated on a really short channel, where you need to really pay attention to your interrupts, and/or make it where you cant interrupt unload. They could also give them more utilities to help them kite melee. An equivalent of a sorc/sage force speed would not be that bad of an idea, both classes do share a healing tree, and a similar kb, why not give commandos a quick speed boost?
