IA (Operative/Medic) has some things to like, just not sure I'm a fan of the whole "cover" deal and launching robots at your friends to heal them.
Since my knowledge is somewhat limited, things will probably wind up differently than I imagine. The best bet is probably to play all three and decide from there, which I'll probably do eventually, but initially deciding (while not falling behind) might be the hard part.
