Mate you were OP accept it. Check my thread from days before the nerf.
Your nerf is badly needed as you are one of the most broken pvp spec in the game. Just 8 hits with an ability that is totally spammable - Necrotic Strike removes 70% of your hp in heals THATS ABSURD. And it is refreshable and its not that every stack works on its own. So Thanks blizz for the nerf… Dont reverse
