If you were to ask me a month ago I would have said a Pally and 4 Shamans. With the nerf/buff/changes to how totems work I have went Pally, 3 shamans, and a moonkin. this is my personal preference I can see value in other combinations as well but this one made most sense to me. Everyone can heal and everyone will be able to out of combat rez when wrath comes out. With the nerf to stacking Crit totems the moonkin aura should help. 2 shamans will be elemental and the last resto, earth shield will be nice. I also have a priest in the dugout as needed and might level a few mages. With RAF and the recently announced 60-70 leveling ease there is no reason why you cant have several team configurations.
