Rework the market system to allow purchase offer listings and eliminate undercutting
I would like to see the market system reworked in such a way that players are able to put up purchase offers like sell offers and that items are not listed plainly and explicitly as they are now.
If anyone here has played Old School Runescape and used the Grand Exchange you can see exactly what I am talking about. You can put up sell or buy offers for items and each item has an average market value. However you cannot see all the listings and their exact amounts, because of this, you don't have people undercutting each other by exactly 1 or 2 gil. Players are able to put up buy offers for a certain price, given the average market value of the item you can choose to go up or down 5% as many times as you want or still set the exact price that you are looking to purchase an item for. As a buyer, you automatically receive a purchase that is at or below your offer and are refunded the remainder.
Being able to put up buy offers makes it so that whenever someone puts up a sell offer that meets someone's buy offer, the item often sells instantly as you do not have to wait for someone to decide to come to the market and look for what you are selling as there would likely already many people that have buy offers set up.
As for not showing sell offers explicitly as they are now, this would eliminate scummy undercutting practices, as im sure many of you know if you are engaged in the market, as the only option for undercutting would be to go below a market average amount.
