What strategy? What I see is AoE nearly NEVER touched by any group I have seen (except SS and Meteor shower). I can find no way to make firestorm work effectively, even with slow and everything I managed to get 4 hits in before they limped out...now is that worth the 15 nrg cost and the long casting time? Supposedly Mark of Pain still works decently, you get some good damage...then every one is running around dodging once the aggro goes out of control, doing no damage at all, at the end Mop might as well not be used.
I don't know why us AoE users are seen as some sort of lazy bum who doesn't want to think. There is a reason why we HAVE to use aggro control with AoE. Look at the end game mussat bosses, bladed aataxes in UW, the grasping insanity in tombs. lvl 28 monsters with like double our hp, infinite nrg, and ridiculous damage. AoE is like the only thing that kills them at a decent speed (next to minions and SS, which is now the new echo nuker). Not everyone has hours on end to kill all those one by one.
So, what's the new incredible strategy? LF MM and SS necro! everywhere. Now let's nerf these and keep nerfing all the high damage skills until everyone are tearing their hair out trying to kill one aataxe.
I hope Anet fix their half done "AI improvement", lower the monster levels! Fix Orion so the henches can be used again! Decrease the cost for AOE! INcrease AOE damage, Range! Add extra effect on them! Anything!
