"You pull, you tank" is a bad mentality

[technole]

Saying "you pull you tank" is a pretty clear statement on the intent to let the dps die.

I also think some of these "you pull you tank people" have not read up on prohibited activities:

Aiding the enemy / Uncooperative behavior / Lethargic behavior
Refers to an act of performing actions that give an advantage to an enemy (monsters, or the opposing team/players in PvP content) by not performing the necessary gameplay required of the situation. This may be combined with combat sabotage as well.

◆Monster Player Kill (MPK)
"MPK" is an act of sending a monster towards another person so that they are knocked out or obstructing another person's gameplay.
