I really can't decide between Commando or Vanguard, and ultimately I think it comes down to I hate Assault Cannons because they're huge and the running animation is terrible, and the pulse cannon sound effect makes my ears bleed so Vanguard's a bit iffy.
I know for Commando DPS (Gunnery, at least), you need Assault Cannons, but it doesn't look like for Combat Medic I'll actually need to use one. If I can heal with a blaster rifle, I'd be happy. Is this possible, or not?
I figure if I can't heal I can always use the Assault tree which seems like it doesn't necessarily require assault cannons either...of course, I'd probably keep one on me just in case.
