Am I supposed to pull wall to wall as a tank on every dungeon?

Yes and No. You should not feel obligated to pull more than you are comfortable with and/or your healer can comfortably deal with.

You will never improve at something without leaving your comfort zone on it. If you do not try, you will not get.

Also, you will never know what people are able to deal with until you try it. I've had so many parties where it's so clear we can handle big pulls, and the tank just refuses, because he's too scared. Some of these runs are still with big pulls, but because the dps or healer pulls the second set of mobs, and then tanks the mobs in front of the tank, who in some cases is throwing a fit so they won't get aggro, yet the dps or healer survives anyways.

I cannot stress this enough, things do not hit hard enough in most dungeons. If a healer can tank 1 pull, you can tank 2.
