I stopped being bored with my shamy+paly team when i killed my first few heroic bosses. As far as fun factor, any of the ranged DPSs can be a lot of fun. And it looks like they all are getting great new talents/skills in WotLK. But 4 SKs and a healer? OMGs ( or do you even need a healer? looks like they keep themselves topped off nicely!
