You see, I've listed reasons that the current system is better for the economy by make it ridiculously hard for RMT (or any player driven corporation) to run a monopoly on goods.
Lol I can run a monopoly on goods, I even have enough gil to do it. The Wards don't stop RMT, hell they don't even slow them down...there's a search feature isn't there? that means there's room for manipulation. The only way to stop monopolization of goods is for congress to pass laws against it, and being that this is a game you'd be hard pressed to get that to happen. The Wards have no redeemable qualities about them, they are cumbersome, they require much more out of you (from putting stuff up for sale to buying stuff) for a lot less in return. I'm sorry, but no matter how you slice it up, the wards stink and will get worse. A Menu system is much better, call it whatever you want, Auction House, Vendor, whatever; as long as it has no NPCs involved and it does the job better.
