You know, recycling old and obsolete or redundant gear should totally be an option in this game.
How about use an Endeavor to recycle one or more pieces of crafted equipment. You get back one non-exotic raw material for every three units used in crafting the item, of a choice used in the creation. So if an item took one bone and two leather, you can recycle it to get back one resource, which can be either bone or leather.
To make it worth the cost in Endeavors you should be able to recycle any number of old items at a time for one Endeavor.
