Our AoE is still stronger than everyone else's given that the only real competitor's AoE (DK) was also nerfed. Relative to other classes, our AoE remains the best. The change seems to really help make certain boss AoE phases less FireNovaFaceRollable.
When they go after our talents Nova-related talents (Echo and UF), that's when it'll be time to fear for our dominance.
