Not sure what aspect of the game you are asking about, since you didn't mention it. In PvE we are OK, not under powered. But in PVP Commando outright SUCKS. If you get jumped by a stealther, and I am not even talking about Operative, let's say you get jumped by an Assasin you can't do anything. Well, you can try, but there is no chance you gonna beat him. Same if you are jumped by Marauder or so. We have very few options to get away. Knockback with snare on 30 secs cooldown, shockstrike Lolz and full auto slows target for 2 seconds.
So yeah in PvP Commandors are very under powered.
