It's already annoying enough when the tank isn't really ready to pull wall to wall, but the expectation is that they 'should', and the tank dies 5 times in a simple dungeon because people would rather kill the tank 5 times than take 3 minutes longer. Annoys the hell out of me. If you want tanks to be available for 'normal' runs, stop abusing the tanks. They WILL quit. I've seen it in too many other games.
