I don't do super pulls as a tank. I feel confident enough that I could do it, I just don't want to because I see it as a negligible gain of time and unnecessary stress on the group.

There was this one tiume, though, where our Healer was obviously over-geared and wanted me to pull more, until he eventually started pulling mobs himself.

So I don't really think "super tanks" are the problem. Players in a hurry are the problem.
