Blizz made the Armory page on the WoW site classier. Now when you highlight an item it tells you where they got it from and if it's from a boss, a general drop rate on it (Low, High, Medium). No huge deal, but it is nice if ya see something now you know where to get it.
Just noticed this feature too. You can highlight the item and off to the side of it theres "find an upgrade" where it tells you where to get a better item.
I click on my primalstrike vest and it tells me there isnt anything in the game better LOL
