Biggest pet peeves when it comes to dungeon runs?

[ForteNightshade]

I don't understand the "gogogogo" mentality either.

Because for the majority of players, dungeons are something they want to get in and out of quickly, especially Expert. They've done these dungeons a bazillion times, few of them are remotely interesting and, in the case of tank and healer specifically, neither role feels useful unless you're pulling the whole room. In fact, healers are completely useless in Expert if you're pulling three mobs at a time. Tanks just have too much mitigation and self-healing to even take the slightest bit of damage. To put this in perspective. Warrior can entirely solo Paglth'an, the newest dungeon released. When dungeons are that non-threatening, most people don't see a reason to pull small. The only exceptions are the lower level ones due to lacking AoE skills and new players not yet realizing how much they can get away with. By 50-60, you see dungeon mobs lack teeth.
