Video was to show mad deeps, was want to show the execution of the profile. Using alter time arcane power, gem before alter time for 100% mana during it(this is experimental, until I get testing in to make a call) scorch and arcane missile weaving and arcane barrage at the very end of alter time. only "AoE" occurring was the secondary effect from nether tempest.
Those numbers are unbuffed and un-hasted, even on a fight like garalon(10 man) I sit around 115-120k DPS.
Non-gimmick fights like feng I did around 90k with my "meh" gear and that was with the outdated scorch weave(using scorch at 80% mana).
The common misconception with arcane is that its AoE sucks, that's poor information coming from the mouth of a inexperienced raider that probably doesent understand why they are doing crap DPS and their using arcane explosion. Arcane Explosion is garbage.
