If DPS pull intentionally, I tend to just stand there. Only once the healers heal will I pick up the mobs, because I don't want my healer dying because my DPS are either stupid, impatient or just plain rude. As tank, I am usually the one who knows what to kill first and why, how to position things so AOE's don't hit my squishier brethren, I am paying attention to pats (if any) as well as knowing how to do surgical pulls so that my healer can DPS as well. I see the DRG pulling everything a lot in the 30-40 range of dungeons, where they seem to think that because they could get away with it in copperbell mines they can do it in Stone Vigil.

I also have to take into account my healer might be new, generally inexperienced with the class or even common sense-defyingly stupid - in which case some pulls I HAVE to make as painless as possible for them to get us through it and I can't do this with DPS doing my pulls for me, it's also rude. Why? Because Sometimes I am distracted, maybe somebody is talking to me and I need 30 seconds of my attention elsewhere. Maybe I've just spilt my drink all over my keyboard and need to quickly wipe it down before it seeps in. Things happen, and while I would love to be able to AFK for pulls in these situations, in many cases the DPS doing the pulling don't even understand enmity well enough to keep multiple targets off the healers. Solo mob? I don't care if the WHM pulls that. It's not going to kill anybody as long as 3/4 of the group are there.

This turned into a longer rant than I had intended
