Give us unused armor skins for transmog
There are so many cool as heck sets, especially from vanilla that have no actual ingame items using them, even though the textures and models are in the game, and are only used by NPCs.
A prime example (but far from the only one) would be the armor that Squire Maltrake uses - the only piece available to players is the chestpiece and it's really damn hard to craft. What if you released some cheap-ish armor bundles with vanity armors that use those wonderful, but unused armor sets to give us transmoggers more material to play around with? Pretty please? :3
