Is this a glitch? How come I don't have the option to change my Akkhan set pieces back to their default look? I'm just curious to see if anyone else has this problem or if blizzard is going to fix it later.
None of the class specific items can be transmogged back to their original art. You also aren't able to transmog in to class specific set items. It was discussed a while back about adding a fix but it was low on the priorities. I don't think that it was intended to ever be able to xmog class set items. Maybe we will see something done about it in 2.1. It'd be nice to see a "reset" option in the xmog part of the enchantress.
