"You pull, you tank" is a bad mentality

[TBerry]

If you playing how you want involves punishing the other players for simply not conforming to your own idea of what correct gameplay is, I'd rather not play with that person at all. And the ToS just so happens to agree with me.

Others running ahead and pulling without consent is not the correct way either.
99% of dungeons I played in as a DPS usually let the tanks pull, and 99% of dungeons I tanked in wait for me to pull. Only exceptions are if the tank dies or one person is still alive, then we go and help that person and then wait for the tank.
In fact if you are really a GNB I can accuse you of being lazy and not doing your job. Letting others bring mobs to you is some weird power trip you have.
