The only reason the economy is how it is now, is because we can see the prices of items. FFXI only showed the last 10 transactions of an item. leaving to practically guess if there was a silly person who put the item up for 1 gil ( that could be a 10k+ item lol), or trying to save money based on the Price History. ( people would even go as far as going 1 gil at a time to buy the lowest price on the button LOL.)

I would like to have FFXI Economy system, so we don't have much "Under cutters". Only reason people under cut is because people know what the other people's price is. If we didn't know it would be very hard to undercut 40 people of the same item.
