Resilience + stamina...that's what you want to have. And a little bit of spell power. For the off-pieces chose the ones that gives you hit rating since you will find yourself in the situation of offensive defense .
Oh and enchant your pieces with spell power and stamina. Lose the spirit in your enchants, get a speed increase either with a meta on head or an enchant on boots. Go WG ang get your enchants for shoulders and head.
Blessed recovery sucks, get full 3/3 rapture. Also I will replace the flash heal glyph with the PW:S one.
