Is anyone else sick of these ridiculously inflated prices on the marketplace?
Well here is a solution, turn it into an auction house. When you put it up for sale people can bid on it. This of course only works for pure gold. Therefore, there you can still trade items, but when you want to sell something for gold it goes on an auction for X amount of time.
In order to stop people using their friends to boost the price, all bids cost a certain amount of money and 5-10% of the ending price goes to the house. This money is then redistributed to poor players who have no monies.
Alternative mentioned in this thread:
Allow items to be put on auction.
