I dunno, Shirley does NOT trust any of them and loves to lord over her false superiority, while the others seem like they can't stand that of her.
Pierce is now pure villain.
Britta seems to get on their nerves with her self righteousness and Annie's so naive that the others seem to have no problems taking advantage of that. And Jeff can take or leave any one of them, and would probably be happier without them (despite having the desire to stick around if only to fix their mistakes, ie, he knows they're losers and thinks they can't function without them).
No a lot to admire in the group. Troy and Abed are the only two with a genuine friendship.
Yeah, the group dynamic is changing. But for the worse, as they discover how much of a self-serving jerk most of them really are.
