Well not everything can be perfect m8
Beside that if these stats are good for sins they may be nbot good for other specs that much
stats per piece dont care, best in slot has a lot haste on it for sin (set pieces, leg bracers, leg boots). It is the whole package what brings the dps. (~675k dps on 900 BiS)
While I do not ...care what the op is complaining about , would it be an amazing thing IF your Tier Armor Stats changed with SPec? Stats to best stat and 2nd OR 3rd best stat.
No need to qq over reforging anymore.
As a Poison rogue , I am carrying 122% Mastery atm at 867 ilvl, I can lose a bit of it and not sweat things, I think.
Mabye wait untill after 7.15 stat rework untill start qq, I agree atm haste is awfull and I rather piss on gear with haste than wear them, but in a month mabye hate is good.
