Its fun to watch when dps thinks its a tank, I usually just go on my merry way and pretend im the dps and attack on target with no tomahawk or over power. then when they have died enough and say what the hell, I just say oh what happened? I thought we where switching roles mr. tank??? then proceed to say, stop pulling and you wont die or get even a wif of agro. if you where on my server id say id go in with you as a healer and whoever was pulling and doing it on purpose, I would let die until they learned the lesson.
