This, and more of this. Druids are silly. Priests are technically tanks since we can't escape, yet druids get PS on a 1 minute cooldown that lasts 12s (oh noes 10% less mitigation). To get a kill on a priest you dispel his bubble/pom/renew etc to make him squishier. If you dispel a druid's stack of hots he gets healed (lifebloom). Then any kind of melee just sits on us (since we're tanks) while a druid goes travel form and prances away.Originally Posted by Berdine
It just seems that they have the best of both worlds, tanking and mobility. Innervate is far easier to use successfully too.
All that said I know priests have their weaknesses because of how powerful they are in some regards.
