Tanking is the most stressful role and healing is second, in my 20 years of MMO experience. How many times have my groups, raids etc wiped because of DPS pulling , etc ... You only really begin to understand the content properly when you spend time tanking. The tank shouldn't be lead around from the nose by DPS, this makes me log out and or stop tanking. If the tank asks you not to pull and you ignore them, then sure, enjoy your death. If the content is hard challenging content, you should not be pulling as anything but the tank or for strategic reasons agreed upon.

At the end of the day I guess it's about tolerance, I just don't have it in me to be dragged around by noobs anymore. I spent years in that position as it is.
