File this one under “how is this in improvement?” I don’t normally talk about game’s individual updates, but the upcoming patch to Warhammer Online, 1.3.6, is revamping the UI of the auction house to better fit the searching needs of the game’s players. As a result of this upgrade, all auctions are standardized to 48 hours, and Mythic has decided to remove the option of bidding on items, opting for a buyout only approach.
According to the WAR Herald, the options being removed are due to lack of popularity, so I won’t question that aspect. I do have to question how removing the aspects altogether, rather than allowing the few who do utilize them, can be an improvement. It is possible, of course, that the new infrastructure of the auction house required some of the options to be removed, but aside from a technical limitation point of view, I don’t believe there is much Mythic can say to convince me “no, this is for your own good.” I feel like I’m talking to the Apple of MMOs.
Personally in the grand majority of MMOs that I have played where an auction house exists, I’ve found myself setting up a tried and true method of selling my wares: start low, set a high buyout amount, and start gathering data on how well the items sell for. On World of Warcraft, this method has become a godsend in selling stacks of cloth and has allowed me to make a substantial amount of gold doing what is essentially a side-job.
Runescape is one of the few MMOs I can think of that only features a buyout option, although the Grand Exchange isn’t billed as an Auction House, and the system of buying and selling is 100% anonymous.
I have a feeling Mythic might offer their players some clarification, and hopefully if enough people ask for it bidding might be returned to the game.

I actually think this is an improvement as a former hardcore WAR player. Even as late as last year before this last round of server merges, AH activity was so low, it was depressing (especially on a newb) to see an item on AH not win it, low movement, with no buyout. Vice versa as a crafter, I put all my stuff up with an addon with a reasonable buy out, and most stuff didn’t sell.
To put it frankly, WAR’s AH is so unused at this point having too many features actually hinders use and makes selling things a pain. I know it seems unintuitive to take away features, but let’s face it — WAR is trucking along but with an unhealthy population in many respects. Making search work well, and a simple buy sell feature is really all that is needed here.
