psychotic goon squad GOOOOOOOOOOOOOOO!!
But seriously, I think bioware wil flesh these characters out more. There WILL be stories behind these folks, they WILL be interesting, and in the end we WILL think they fit. Sure they may not be as likeable as some of the others, but most likely that is the point, the story is heading in a darker direction, logically some of the new cats that will see coming along for the ride will be as well (hurray for run on sentences).
ALso, I would love to see one of those elephant like things (you know the ones that state their emotions when they talk) as a party member. It's a ridiculous dream, but i think it'd be awesome, use as a mount or something, have him make deadpan statesments like "paralyzing fear, we should retreat" in the middle of a fight. awesome.
