I'd say, get some T6 and avoidance heavy pieces, stick to the holy shield libram, stick to deflection still, and burn the excessive avoidance by kitting your helm, shoulder, and hands for 30 more stamina pre-scaling.
Honestly, this new kit alone made prot pally itemisation even MORE nightmare-ish than it already is. You thought you already have too much avoidance to worry about uncrushability again ever past Magtheridon gear or so. Hah, you are not prepared!
