Trading Post requires a few changes
On the first issue: No argument there.
On the second, that would just make things even more confusing for new players by making listing for a lower price earn more money. Especially when filling a buy order means they get more coin than vendoring, but listing a sell order doesn’t. Sure, ANET could fix this with a good interface design, but we are talking about a company that thinks the listing fee isn’t part of the ‘profit’ from selling an item.
