I almost never have a tank that doesn't pull big groups even in the new stuff, and they never ask. Then they blame me when they don't use cooldowns because "Muh deeps", I blow all my cooldowns trying to keep them alive, still have to chain cast to heal their yo-yoing health, and they still die. I had hoped that with mobs hitting harder in this expansion tanks would realize that maybe they don't want to pull like insane monkeys, but unfortunately that hasn't been the case.
