Your stats look good bro. 50% block, 10% dodge, 13% parry
I prefer mastery food over parry food, but that is me. food is food, just pick one really.
Blitz- not good...the stun can really hurt you on some fights
def drop that for field dressing, increased healing is a win.
i would also drop 1 off war academy and pick up piercing howl...another win.
Gloves should be mastery
bracers should be dodge
I use this rule of thumb
Blue - stam+mastery
Red - Parry+Mastery
Yellow - Mastery
unless your itemization is bad and you need to increase a stat... like i sold my BOE shoulders on accident cleaning my bags and and didnt realize it till it was too late so i have to use more pure mastery gems to get the numbers i want till i get my tier chest and helm off maloriak.
Unfortunately i have been working late so i dont get on till raid time and haven't done the VP daily in weeks and no tank helm has dropped from either boss so far for us and we have several kills on both.
I like to keep my numbers at 10% dodge, 15% parry, and 50% block...as a minimum
I dont see why you would stack stamina tho even tho you met your numbers
other than that looks good
