I understand people like the idea of setting up their own shops, but the way real Bazaars (let's admit it, they're trying for a bazaar here) worked was like a flea market. You would bring the things you had, sell them to a merchant, and then that person would turn it around and sell it for a profit. I'm not saying the wards should be like that. In FFXIV the "merchants" should be hired to sell for you, and then you give them a tax for their services. Not EVERYONE in the city has the potential to be a merchant. The cities need to have NPCs specifically designed for selling your items. Can have a few in the same zone, spread out a bit to reduce area lag which seems to be such a big problem for people right now.

Also, I agree that it doesn't matter how long it takes. What matters to me is that it's unorganized and unstable.
