I'd bet that the people using that system, aren't really participating much in the standard Guild Vendor Economy to start with. (if they were, why would they bother with that mod, after all).
So, I can't see it having much effect on the regular economy. /shrug
Yeah, rarely do good sellers complain about trade guilds or the trading system. The ones that complain about it are most often the small fries who don't really want to try and get kicked for pitiful sales because it cuts into their pvping time or what not. Now here is going to come someone saying they sell tons every week in a guild with no standards. Well here is a unicorn sticker for that person for being such a rare special case, because the reason the guilds in the best spots all have minimum standards is because they make room to get the best sellers on their roster they can because the best sellers want the best locations. Like it or not there are plenty of people that don't want an even playing field. They want their goods to be front and center. They like it competitive and they'll do what they can to keep it that way and plan on winning.
I don't mind it, if you are trying to force ZOS to disable it then you might as well disable every other mod out there, you wouldn't want that now would you?
You can't have it both ways in having some mods and not having others. If alot of people are using (which I am not) then that shows you that people are in favour of having a global auction house in game. If they don't use it then there isn't a problem as it won't do very well.
I originally liked the idea of an auction house because I used to play WoW but I'm unsure about it now.
Today i have been receiving four mails so far with the Subject "Nirn Auction House Order"
I did not order anything
I do not know any of these people
All sent random stuff with a huge C.O.D. fee
Feels like scam to me.
/edit: I do not use the addon
