I've completely given up on shamans who claim they are awesome tank healers and are equal to paladins. You cannot have much of a brain, specially now with the four set bonus, if you still claim that, it's complete and utter bullshit.
We are a support class/spec, we support the raid healing and we support the tank healing when its needed, we are versatile life savers, overall solid healers, not the best, we will not be topping the healing meters (unless that's all we care about which I hope it aint for most of you), we will be making sure we can heal people fast who goes dangerously low.
If you wanna play a tank healer, reroll paladin.
