Why can't you auction them? It says nothing about not being able to trade them, is it a bug or something?
It's just starting to annoy me cause I have NEVER seen ANY Rogue Desert Scorpion (nor Storm now that I think) armor and the only way to get them ATM is to buy from other players or somehow find yourself, which kinda sucks for the reasons I stated at the start of my earlier sentence.
If you could auction them there'd be no problem getting your hands on this equipment as long as you got the money. You can auction the weapons so why not the armor?
