I was hoping someone would note the "Flare" treatment a lot of aoes got. No issues using aoe skills on reasonable pulls, but when you pull half the dungeon, anything after #5 is getting half damage, and I'd call that pretty inefficient.

To clarify, do your big pulls, but keep them reasonable. At one point it's more of a disservice to the entire party than it is helpful, especially if the tank or healer can't keep up. I've had tanks nearly die in the span of an Aero 3 cast, and that's just not right.
