Oh I wholeheartedly agree on the teamwork aspect. But right now on test server, a tank's pulls break a controller's CC effect almost instantly. Some effects that could last are transformations like Horrific Visage. But if you have a tank who spams pulls....it will make CC almost nullified and it makes the job harder on everyone with non-stunned NPCs. A small hiccup in a sense. Either way, a tanks job is to keep the attention of the enemies on him than rather his teammates. Pulls are there for a quick grab but either way, if you taunted that enemy....he will come to you eventually maybe not immediately. So once the enemy is taunted, you did your first part of the job....the other part of the job is to survive. Controllers can also move/pull NPCs into place as well, each controlling class has pulls.
