PVP however this basically is the complete end to any viability for any spec. We don't have enough defenses nor damage right now so nerfing our control (blood fear was strong and propping up the class so while it may have needed to change we needed big buffs elsewhere), our damage/pressure, and our defenses we got killed through anyhow. Mages keep the *longer* blanket silence on CS but locks lose our shorter version? You basically will never be able to cast a fear again.
Look at macro pvp stats and everything below locks (rogue/monk) got majorly buffed for pvp while locks were gutted. We are borderline non viable now and gutting control, defense, and damage is not recoverable.
A whole class that is pvp non viable....like don't even bother to try to participate in this half of the game...is not okay. Blizzard demonstrats its complete ignorance for pvp design with these patch notes. Either someone prominent on the dev team has some personal grudge against the class (or the former dev who was a patron of the class) and can't be professional enough to divorce personal from professional in terms of quality of work or they are completely ignorant.
