I recently completed the NE heritage quest line to receive the armor and weapons. I clicked the items in my bag to learn the appearances and they all show in my collection on the appearances tab under 1H swords. However when I go to transmog them onto my character only the armor set shows up. I have tried on both my night elf rogue and a night elf demon hunter and neither can get them to show at the transmogrifier. I know they are usable because my wife was able to transmog them onto her warrior. The specific items are: Glaive of the Blood Moon, Moonlight Glaive, and Duskrune Glaive.
