So.. i just got my first toxic party

[Bhearil]

That's not toxic, chain pulling trash groups is the norm @70, in my experience maybe out of every 50 runs 1 run is a tank that single group kills and he is a newbie to dungeon 9 out of 10 times(or a really bad tank that 1 time). You are not suppose to pull kill one trash group at a time, but drag trash groups until you hit the "trash barrier wall" (ie walls that break when you kill all trash). Of course if your tank/healer/dps suck you pull less.

Thats not true, depending on how things go, the team might ask the tank to pull harder (or the opposite if the tank is going too hammy), but a healer pulling mobs on purpose is a dick move. If when im tanking some smartass thinks thats the proper way to ask for a bigger pull, ill keep shirking his ass as well as not tanking his mobs so he learns to be more polite about asking things.

If the tank is not pulling more might be for a reason and forcing him to do it like it or not is not the way to go. Another thing is talk about it and the tank agreeing to pull more. Otherwise is the old "you lure you tank it"
