Druids are baaaad main healers for the later stuff; they can heal okay but HT is too damn slow and hots don't heal enough to counter any burst dmg whatsoever. Let the Druid tank(which they excel at and aren't TOO bad at multimob tanking with swipe and tab mauling + demor roar to soften the blows a lil and more hp/armor than any pala could ever hope to get + no mana reliance); let your priest heal, making it DruTank HealPriest, lock lock hunter; locks can SS/HS and curse of weakness if absolutely necessary or fear to save priest
