lol ok, i realy dont have time to explain it when you simply refuse to even do the math and contradict yourself in 2 diferent posts.
Its ether the buy orders will raise making it possible for the "effectively higher buy order than lowest sell orders" and in turn decrease the gab between the buy and sell orders or " Basically, it would increase the gap between buy and sell orders." , again whatever way you take it it is till contradicting yourself.
The sugestion was made in order to affect the 85.9% of the items curently trading at positive ROI aka the buy price is way lower then the sale price , and with the aim to get the buyers to raise there prices by having a incentive on the seller side to fulfill orders. Making a better distribution of the losses ocuring from a sale, aka more gold for the seller with minimal risk to the buyer. Where now there is no incentive of the buyer to raise the price any more then 1 coper over the buy price curently listed because there is little incentive on the seller(except time) to sell at the buy price
As suggestion is not agreed upon by the comunity i do not see the point in duscussion it further.
