Large pulls VS Small pulls... in leveling dungeons?

[Nikolas]

I pull each mob as they come in the leveling and the 70 dungeons. Nice and steady. I really don't like it when it takes three times longer to kill multiple mobs than it does to kill them one group at a time. Also, dead. Don't like being dead.

3 mobs will die as fast as 6 mobs if DPS use their AOE skills. No point to drag the dungeon twice longer.
