Yeah I’ve seen it and I like it, just I suggested this as it already exists in the game. Two of our legendaries are already copied from there. Knowing the history of adding borrowed power from the past maybe it comes next expansion? xD

Nerfed offensive CDs in PvP.
Does any other spec have them nerfed in PvP? Rogue’s Shadow Dance and Symbols of Death also give %Damage done without being reduced in PvP environments and have much lower cooldown.
Arcane relies much on CDs to land a kill on an already hard-casting spec with one school.
