With a paladin and 4 shaman team, having one dedicated healer and a second shaman ready to go to heal has never failed me yet and still proves to be very effective when the healing gets rough. 4x healing totems, 2x chain heal and now with the over powered word of glory 25k heals with a priest shield, and never running out of mana, the only thing that can kill you are mechanics you are not prepared for.
