I dont think this has been brought up before but I didnt find anything under search. I am actualy quite surprised no one else has noticed yet. Singular Focus - KILLS Crit Bonus if you take the Prestige AA BladeMaster for 5 AE - 1 Crit Bonus. I was sitting at 295 Crit Bonus and it will drop me to 95% Crit Bonus after activating it. It is not jsut a visual bug as I have tested the damage out put differences.
