The question is, why not make everything that have limited use to it.

That means all refines, clothing, threads, equipment upgrade mats and whatever else.

Even the farm-able stuff, like the equipment upgrade mats(not scroll, the others), should be fine, as their is an income limit based on stamina. Perhaps a lower value but a trade in value would be nice (I'm finally done and I have a lot left over)

The real question is, is there an actual REASON why some of them aren't in there, or are they just dragging their feet because they are not motivated.
