I turn off Tank stance if a DPS wants to pull groups ahead of me. I don't mind pulling wall to wall to much If I know my healer can handle it. I typically ask healer what his pace is. I have encountered so many healers that just cant seem to keep up in duty finder.

When I dps, I purposely refuse to do aoe spells when I dps when there is a guy who yells at the healer for not keeping up with the tank
