Here is a first stab. Rankings used were streight from Loot-Rank using the standard Prot Warrior Template. The order of the items stayed essentially the same using their formulas.
I will need moderator type to either update the top post or I can just keep plugging away and create a new thread when I get a few sections finished.
Backs
Getting your paws on a
Cloak of Peaceful Resolutions is one of the reasons why it's good to rush your Wyrmrest Accord reputation to revered as fast as possible. It's very easy obtainable and will last you until you grind enough 25-man badges to get a
Platinum Mesh Cloak. Personally I'm not going to waste gold on the BOE crafted one, especially since it lacks Defense which are pretty hard to get enough of already.

As it looks now, the Defense Rating and the Armor enchants are pretty equal. What you chose depends on whether you're into maximizing your effective health or your avoidance. The +16 Agility enchant is a nice alternative in case you want to add some threat too.

+22 Agility
Mighty Armor (1350)
+225 Armor
