There is no way to feel powerful as a Tank, you can dodge all the AoE, pop all CD in the right time, it be ruined by a bad healer and you still going to hit the floor. The best you can do is yell at him, then it come to an argument about who is bad... is it the Tank or the healer? Who come first EGG or Chicken? Pointless as hell.

The Job should not depend that much on healer. Hey, am a godlike tank, but healer are holding my BALL, RARW!! i mean seriously. Is unquestionable why Tank class is so boring and sad to play.

Give PLD some healing power, at least to keep himself alive, add more random dmg to DPS to keep healer job busy, problem solve, everyone happy. Now you can have super good tank, average tank that require healer attention and Bad tank that have no clue how to play his job.

A good healer can keep a BAD tank alive, they just need to be PRO.
The best tank in the world simply can't stay alive with a BAD healer, i think that enough said.
