I will admit the idea is bad but considering how everyone likes to
jack up prices , i mean buying zeni would lower prices for other
players. Would have no means to sell high price at all . Figure if cashers want to buy sell dogis to make cash, you might as well make an option to buy Zeni for them lazy cashers. that way For Fun accessory type items are cheaper , while money is made by gear but only ever so slightly . Figure the lower AH prices are the better for new players and if cashers want to cash so they can make zeni just let them buy zeni . problem solved.
It is the other way round, the easier is to get zeni, the higher are the prices. It makes no sense that the prices go down when people have more money.
