My 5x Shaman team is just short of 68 now, the only real irritation is like has been stated, the high collection quests with poor drop rates makes me want to gouge my eyes out with a blow torch.
On a pleasant note, I am really liking the 5 man shaman team , one is resto the others are all elemental, it is insane how easy it is to drop a mob, elite or otherwise, its a lot of fun.
