Please keep in mind that this is not 100% official or confirmed, but I believe it to be. I'm assuming it'll be similar to AQ40 gear. There is currently no possible way to say, this set is for Class X and this set is for Class Y, except I'm sure you can tell that the robes will be for casters :P All filmed on a LIVE server, in the famous zone of Hyjal! Enjoy :)
The filefront live stream is good, but downloading it is so much better! ^_^.
