I found an AWESOME site that is meant to help you determine what gear is best for you. It is www.lootrank.com. Make sure you click the sample templates link up top and find your class/spec. Then in the middle select where you want the loot options to pull from then hit View Loot Rankings. If you want you get the items from your armory and it will tell ya what item is better (and by how much) in comparison to what you have on now.
