On one silver play through (which we failed at on the last wave before extraction), I watched as a Vanguard took down whole groups of mobs without any help. Charge to that AoE one, charge then AoE, charge then AoE. They were always moving, and always damaging groups of enemies. Was crazy.
For anyone looking for lists of the class/race distinctions, as well as available weapons, the wiki page
has already updated a lot of information, with detailed information about the weapons as well as strategy suggestions. Worth checking out for anyone thinking about builds. Doesn't have the N7 gear yet, but that's not surprising. The info is surprisingly detailed, too.
Anyways, you all are horrible, @#%^ed up people
Never underestimate the healing power of a massive dong.
