Give Commandos/Mercs a passive skill which makes it possible to cast abilities while on the move. Always.
Pros
-Increased survivability (kite - cast, kite - cast!).
-Increased damage while on the move.
-It's Commando/Merc exclusive (Crazy thought huh?).
-It's gonna look bad-***.
-Commando/Merc healers will have an easier time keeping up.
Trade-offs
-Damage/Heals stays where it is (Fine by me, even with 2.0).
-Still interruptible (fair in my opinion).
I admitt there's gonna have to be some tweaking here and there but still, Commandos/Mercs need this kind of skill to be competitive as it is. The discussion about interrupt immunity during hold the line and lower cooldown on this and that are cool ideas but merely band-aids.
I know it's been mentioned before but hey, why not? Commandos/Mercs are in a bad position as it is both on Live and PTS. Throw us a bone (or Corpse in this case) Bioware!
