Wanted: Tomestone and nuts item refunds
In WoW, similar token purchases can be refunded for the full price for one hour, as long as they weren't equipped and soulbound. I just made a tomestone item purchase, then discovered I already had the augmented version in my armory chest, so I just wasted 495 Astronomy tomestones.
I guess the issue here is that there's no soulbinding concept to let the system know you've equipped the item. Without that, people could buy gear, use it for an hour, then refund it and then buy another piece for a different job with the same tomestones.
