Haven't honestly had issues Tanking. Sure, things can irk me but in the end, it's a game and it's not some random anon on this game being an asshat that's going to deter me away from playing the class.

I play the class, I think I do a good job (CDs are normally on rotation unless absolutely needed for a specific attack, Aggro is pretty much constant on me, don't go and cleave things in the face...), so that's all that I care for. Also, most of the time, I can take criticism very well so I tend to grow and learn from it.

Most people don't have the thick skin to deal with tanking. Period. It's a more stressful environment if you let it be. Otherwise, learn your role, preform well, don't stand in the fire...oh wait, that sounds like any class in any MMO really.
