I have seen a tank blame the DPS in M3 for not taking down the heart fast enough when the tank was the one who refused to move the boss (let's just say I'm never selecting English only again), but other than that? No, I'm not even sure we're playing the same game, it's always the healer or tank to take the blame unless the DPS did mess up, healer and tank do take more hate but they're a mess up from them can result in a wipe. This is coming from someone who only plays DPS. Sure, when it comes to DPS checks the DPS are blamed, but in that case some of them are at fault.
