I know I'm fairly new here, but I do not find the shopping part as much fun as others might. It's the first and maybe only thing I'd change if it were up to me because it's way more frustrating than fun.
The Bronze vendors are usually empty so I stopped visiting them. And many sellers mislabel their vendors' pouches, or don't label them at all, so you end up opening up every box and pouch anyway. At least I've learned to hover over them to make sure they're aren't empty. And many vendors have useless or no names so that doesn't help.
And sure, the staff can monitor vendors but that has to be a pain. They don't seem to do it that often. So maybe things are better for a couple of days, but it doesn't take long for things to start to get annoying again for shoppers.
One complaint I've seen is sellers who "scam" buyers with over-priced goods. The best antidote to that is information. Posting price guides is too much work to update, and who wants to take the time? I'm guessing no one, because I've heard people suggest them but no one has made one. A vendor search would fix that.
Even if the search only worked within a certain radius it would help. It would be awesome if you could just ask the "mall manager" whether certain items were in stock nearby or not.
Sounds like the decision is made and set in stone, so I don't expect thnigs to change. It would be nice, though.
