I dont have beta, but aren't these current nerfs aimed towards lvl 110? Also I heard from someone that blizzard doesnt do seperate pvp or pve finetuning anymore... I'm confused what made them change their approach. Now everytime pvp kneejerk reactions will be get to the pve side as well.
Also Subtlety has remained infamously underplayed despite assassination getting isnane amount of nerfs over during the course of legion. Despite these nerfs, rogues flock to Assassination due to it being easy to play wich in itself is a huge advantage.
