What would you guys think of Transmorgrification being applied to the equipment slot itself and not the gear put in it? You can switch gear around but the transmog itself does not change.
this would probably require a lot of code changing and new code that is probably completely unnecessary for such a minor convenience. Plus people with more than one gear set for different spec roles (which is less of an issue with the spec specific gear we have these days but not totally eliminated) will be at a disadvantage in turn.
Ofcourse this could be included with the future transmorg wardrobe system/ui improvements blizz mentioned they would some day do. With options that eliminate the above disadvantage.
