Sell stuff for resources

So currently I have a incredible amount of items. Artifacts, materials, scrolls, sigils, cores etc… Many of them I will never use, or will only need a few of.

Thus I’d like to propose being able to sell unwanted stuff for resources. Could be sold to Bynine for instance, maybe even something like sell 3 cores for 1 exalted emblem. Or if that is too much just assign a value to something. Like 2000 resources per core.

Personally this would be a awesome feature as I like to have a cleanish inventory, but hate to throw stuff out. And there are a lot of times where I just need that extra 1k granite to do something and I have to go out, do a few battles then go back. Being able to sell stuff would be a excellent alternative in those situations.
