Heck, give back the Stockstrike KB and increase Cryo Grenade's range and that would make a pretty nice difference for starters. Both of those are simple fixes, all things considered.
The only time I run my Commando these days is for Daily Comms and when some friends want to run lvl 50 stuff Republic-side, otherwise he collects dust.
I agree bringing those 2 back would make a difference but it would only be a slight difference and we would be basically back where we started. It certainly would help to bring them back, especially cryo grenade (over 10 meters), but i also think we need more/better escape/utility abilities. Thx for the feedback.
