Topic "Here's hoping for buffs to our AOE"
The best way to make AoE mechanics interesting is by making them required in some cases (or at least a lot more effectve, ie generic trash pulls), and devastating in others. Cata still has boring trash; but there will be some cases in which AoE is Very Bad.
In ICC, AoE trash is kinda boring. The best way to make AoE interesting would be to mix in some pulls where AoE is bad, while still leaving some packs where it works. But keep in mind that Blizz has already said they are worried about random heroics difficulties.
