@Murzerker - Thanks, that’s nice of you to say. Transmogs may be only cosmetic but it is another aspect of the game to enjoy.
The Barb yellow wings came from a purchase a while back of Overwatch that came with that purchase - It looks like a Sader but it’s a barb. There is a transmog set in the normal lower end gameplay pickup that has that all metal look too which is cool that adds to it.
If they let us color the glow of the weapons and off-hand and the base color of the pets, we could all have a massive variety of transmogs.
