Dr. Lokins, please (IA healer companion).
man, that one.
Also Talos (S'Inq healer), because he's so charmingly quirky and also wonderfully complex: A pretty hard-line Imperial patriot, but also a really nice guy --no, not "Nice-Guy" in the creeper (Ummm....Corso? As your best "bro," I think it's time you and I had a little talk about a few things...) sense, a genuinely nice guy
-- with the most delightful intellect.
Andi Revel, too:
Because well-geared Revel + Lightning Sorc = pure poetry in motion as far as kill-speed goes, and I just love his growl everytime he does his version of Unload/SpeedShots: "How's THIS fer shooting!"
