I am currently doing pretty well with a druid tank. They made druid tanks a bit more AOE friendly, and some glyphs can help too, to add more multi target attacks. Granted I am using Demo locks, so sometimes I have the felguards OT a mob or 3, but even if I just tankem all with the druid, everything works out fine. I do have to heal more on the druid that way, it sure is nice to spread the dmg out over 3 6000 hp tanks And considering I'm healing with a shadow priest... for most fights, I just rotate in and out of shadow spells, to apply dots, and heal, and it's working out fine.

But my main is still a paladin tank.
