Ok so I don’t know who knows this, but I didn’t and I have to share!
Armor vendors sell stat-less Backpack Straps now for back skins! No more buying Cheetah Charr Backpack Sets on the Trading Post for me!
What are these useful for now the wardrobe is in?
You have to have an item to put a back skin onto, even with the wardrobe. You can’t just transmute a skin onto nothingness.
Until now, the only way to get a useable back item pre-level-33, when you could get one by doing personal story up to that point, was to buy one of the backpack sets off the TP and use the backpack straps out of it to transmute the skin you wanted on your low level character onto. This makes it so you can put a back skin on someone low level for 8 copper - much easier and cheaper.
Ah ofc, I forgot about non-lv30 characters, been a while since I geared one with shiny things :p
