Could we get the ability to make bids on items in the Auction House? Something like how in the old-school maplestory, when you opened up shop in the Free Market, people could leave comments with offers if they wanted the item, but needed to haggle. Maybe implement a system that you place an amount of meso down instead of a whole comment to prevent people from harassing others though.
