I've been playing since Alpha and do agree there needs to be a change in the way we are allowed to sell our goods.
The guild stores / trader are a nice concept and different than most games. But its a major flaw in an MMO. More than 9/10 of guilds out there won't have a guild trader. You'd have to be in as many trade guilds as you can, just to sell stuff. These guilds are the worst for they are only for trading. There is hardly any socialization within them, making friends is impossible, yet alone finding people to do groups or other things within this type of guild. You also have to spend gold to the guild so the guild can get or keep a guild trader. That is gold you lose. (i.e. Lottery, in-guild auctions and just donating). Some even require you to pay guild dues in order to stay in the guild. There is also a lot of guild hoping, as when a guild loses their guild trader, people drop guild and look for another that has a guild trader. Most of these type of guilds have an inactive policy of 7 days to 30 days and you get the boot to make room for more gold payers to get or keep the trader. Again hard to make friends with this system.
I do like the idea but there just isn't enough Guild merchants to go around. It would be better if there was at least 10 times more of them.
So I say keep this Guild Store / Merchant system but put in a true auction house. One that has NO buyout function and at minimum of 3-5 day auctions. Also only allow certain items (high value items) in the auction house. Also with a limit to how many items you can put into the action house. Something like 10 - 15 would be best. Mainly to keep the traders useful and to keep out all those stack-able, single item posts that take up auction space, out.
This would also be something unique as most MMO have a buyout in their auction houses. I'm not even sure if any MMO has a true Auction house. I've never seen one. I've played MMO's for over 20 years now and I've not seen an auction house without a buyout feature.
EDIT: Look at this from a sellers point of view. You can get the most profit from your most valued items and there would be no undercutting of prices. You set a price and the players would control the market by bidding only what they feel its worth.
From a buyers point of view, yes you may have to wait a few days till the action is over but you at least know the item isn't over priced because its the players market that set the price. Like when you go to a guild trader and buy something for say 10k and find out in many other guild traders that the item sells for 2k. If you don't get the one you bid on, you can always bid on another like it later with a better idea on how much it'l be. Also you wouldn't have to keep going from town to town looking at all those guild Traders for the high value items you're looking for.
