"Swift completion" is relative to the game, not the community

The funny thing is that how fast you run a dungeon is more about a healer than a tank.
Yeah the tank is the one pulling and getting all the aggro but at the end of the day it's about how much the healer is comfortable at healing it all.
Wanting to get the most mob you can is not only faster but challenging. I mean, there is no reason you wouldn't want to pull more unless the healer can't keep up.
If you as a tank don't feel safe to do it, that's ok, but don't be so hard on yourself and try things.

It's so fun when I get a healer that says "pull them all" and I do it even when it looks like we can't survive it.

It's about the whole party, not one role or individual. Strong DPS melt packs making big pulls easier and faster, strong tanks give everyone the stability to perform and strong healers give the tank confidence. Obviously tanks and healers also put out decent DPS as well as soon as everything else is taken care of.
