This is why I sorta-kinda abandoned my DRK to level some DPS and healers instead.

Everyone's a goddamned critic when it comes to tanking. If I tank the boss over there, someone gets mad and says I'm the worst tank ever and I should tank it over here. If I tank it over here, the next run someone will get mad and say I should be tanking it over there. :P

Move out of a red zone and some monk throws a hissy fit because his Dragonboot Shinekick had 10 less potency or something because the mob turned. Pull some mobs and get yelled at because if we had snuck over that rock and under the tree and up the hill we could have skipped it and saved 15 seconds, but skip a mob later and get yelled at because the Bard in the group really wants XP.

Every little thing is a point of contention with some people when you're tanking.
