On my monks it shows up as learned, and in the mog closet when visiting a transmogrifier. But it can’t be clicked on, and viewing it in dressing room shows it with a red name, with the text reading it is unusable to this character.
The 2hander seems fine on my DK.
UPDATE: It can be clicked on in the transmogrifier, just not in the standard mog closet. It’s still showing as red in the dressing room, to my priest as well as my monk.
UPDATE 2: Ok, now I can click on it in the closet… maybe I need to rewrite this report… still a red name in the dressing room. I have relogged a couple times since the original report.
