Armory updates, find an upgrade

Blizz just made some upgrades to the armory, very exciting stuff. You can now search for upgrades.

will now return a list of items that are an upgrade for the character for that item slot. So

http://armory.worldofwarcraft.com/search.xml?searchType=items&pr=Bloodhoof&pn=Castlereagh&pi=27423

Shows all the cloak upgrades I could get and where to get them. I'm seeing using this to build a list of locations and boss targets you need to go for upgrades. I'm not clear if it includes my current build for the calculations. But as a hunter, agility, crit, and attack power are what I need. It adds the "use" abilities of items to the rankings, that's cool. Unfortunately the gear you get by turning in tokens is listed as "vendor" instead of naming the boss that drops the token. And items that are created don't say by what profession (it's usually obvious, but like a leatherworker and a blacksmith can both make mail armor).

UPDATE: The armory upgrade finder DOES take spec (or current stats) into account. I looked up a 40/21/0 mage and the search modifiers were spellDamage, intellect, spellCritRating, stamina, spirit. A 0/0/61 mage was spellDamage, intellect, stamina.
