So from what I'm reading here, improvements could be
You can sell items in bulk. The buyer sometimes gets a better deal this way and the seller can off load more of their items.
Being able to make bulk Auction listings, perhaps under the username of the seller
Player interaction? (Buyer and seller conversations)
-I like doing business with people. Nothing like a good deal that is agreed upon by chatmail. Nice. You can add a greeting and cheers to the deal, which you cannot do in an automated auction.
An auction graffiti wall where both buyers and sellers could type would be a possibility to help with Player interaction
I still want my combined store, with rentals auctions and instas all in the same place.
I think that is a fine idea as well, personal user stores
I would like the auction house a little better if there were a way to enter something you are looking to purchase and people could click a "wanted items" link and see what the community is looking for because items people want may get over looked via the fs/wtb threads.
A "currently in demand" sort of thing? Yeah, that would be pretty cool. I agree, when you look through FS/WTB threads it is very easy to overlook items that you may have wanted to purchase.
This isn't necessarily true since you have to always pay a posting fee. You might have to list your item several times to get the price you want which can equal a way higher fee. Noobs tend to do this a lot when trying to sell tattoos.
IMO, only charging a fraction of the auction fee unless the item actually sells would go a long way here. One of the primary reasons that I don't use auctions is because a failed auction costs the fee, while a failed FS/WTB post costs 2K for the entirety of what you're selling.
Fees only being charged when your auction sells would fix this
It would be really nice to get a revamping of the Auctions with some of these feature improvements. :) A lot of them are Very Good Ideas.
