Why not use:
Banners (blademaster style)
Ammo pouchs (hunters)
Totems (Baine)
Moonglaive (night Elf)
Toolbox (gnomes-Goblins)
Flamethrower
Plague canisters (Forsaken)
Alcohol keg (brewmaster)
Jacket (Thrall new model)
Travelbags
Spears with skulls (Darkspear style)
Weaponholders
Magical aura's glow in the back (Naruu - Blood Elf phoenix)
I see alot of options to use items in this slot yet they only use cloaks? Why not make this item slot more fun with more transmog and item options and just keep it covered with cloaks that look like carpets.
