Okay, so I have been testing the auctions and the suggested prices for things. And there is something that works against people wanting to sell certain things.
For instance.. the suggested price for a chunk of shiny is 10 each. Thus if you have 50 chunks you get 500 currents.
On the other hand the suggested price for shiny element is 1 each. When you grind 50 chunks of shiny, you only get 130 shiny element. That way if you sell the chunks you make 500, but if you grind it and sell the elements, it gets reduced to 130 currents. It makes no sense. The suggested price for elements should be AT LEAST 10 each, and 12 if you want to get people grinding and auctioning more. That way it would be worth it to spend energy and time grinding.
