Basic Economics

[kukurumei]

Only thing that comes to mind after reading this thread is that you must be trying to sell undesireable goods.

then there is something wrong with the craft system, drop system, or other system.

There should be no such thing as an undesirable item. There is such a thing as a unprofitable good, which would get NPCed, but that just means it's chink the system.

So much stuff NPCed and not going to wards means there's not a chink, but a bleeding black hole.

It's a very simple rational, that explanations like that do nothing to explain why it should be, but why it shouldn't be. It's simply wrong from an economic point of view, of output that doesn't perform.
