[Theadan]

HI

I would like to know if I have to reforge some of my item to have mastery rating.
Wich stat have I to change? Dodge? Expertize? wich one?

Another question may be that i have wrong spec.
is ok this new spec?

(or may be i have to keep the talent for consacration instead of the upgrade for the range of judgement)

thanks for any reply ^^
plz help me to understand

First reforge all your hit gear, then go on to dodge until it is lower than parry(at which point reforge whichever stat is higher)
Spec I would drop Grand Crusader and put 1 point into hallowed ground and one into divine guardian
Also change the expertise gem in your libram to a solid majestic zircon
