If I am tanking and you pull as a dps, I am going to call you out on it and if you continue doing it I am going to either kick you or leave.
It's extremely frustrating and shows disrespect for the tank imo.

As a tank one of your jobs is to make sure that everyone is there and ready, a lot of the time when it's a dps just running in and pulling we get killed because I've noticed that the healer is afk.
And even if that isn't the case it's still annoying, and there's no reason to do it even because I don't pull slowly to begin with.

'' If you pull it, you tank it '' is my attitude but I don't let people die if they do it the first time.
I'll probably only let them die the third time, because at that point I know that they're not listening and won't stop.
