I'll admit, when i run with friends, and I decide to DPS, I go all out. We've made a challenge to each other, see who can pull off the tank(we all have ilvl50+ tanks). BLM, I can do it on single targets about 70% of the time in dungeons.

when I tank, he does it right back to me as a bard, or as a healer (medica 2 spam!) it's a nice meta game, see how hard it is to keep aggro.

but in DF..or really just DF, DPSing, I make sure to give a little window to the tank, then if I pull more than twice off them, i throttle back, slow the rotation.

In DF if I tank (it was my main originally) in 8man, i better not pull off the MT, you call MT, you better hold it against me. and same for MT, if the OT pulls off me, it's time for me to step down.

It's much for people to do their roles, if you can't, then don't be that role..it's a role..playing..game.
