Yeah, I used it before Christmas for a bundle, WoWHead's a little behind :-P.
Did anyone else noticed that you can also disenchant old expansions stuff in the Garrison Enchanting Hut(level 3 only?) now?
It always seems that Blizzard doesn't like people having fun, but the probable reason is to force players into groups to do the older raids. This, of course, negates the ability to solo old content.
