I dont really care how many companions, what classes or races we get ...
I only hope we will have enough tanks, healers, and crowd controlers ... for every possible gameplay. :-/
I would hate to find out that my evil/good character will have no cleric, nor paladin, or druid ... or w/e else can heal properly ... just bcs none of them can stand him.

But if i recall it corectly, there should be some mercenaries, that should be "allways aviable" so that kinda solves it.
