I think it depends a bit. I've seen impatient dps and healers pulling everything in an attempt to get a sprout tank to wall to wall levelling dungeons and it's just a kinda shit experience for everyone. The tank doesn't learn, and the run is usually slower due to an inevitable wipe.

Though actually that said- Yeah maybe "You pull it you tank it" should be replaced with "If they keep pulling after the tank asks them to slow down kick them"?
