With just a couple of days to go before Blizzard disables the remote auction house app for World of Warcraft, the studio pretty much has extinguished all hope that users will see it return.
“The web/mobile auction had a lot more issues with keeping it up than it was really worth for the small amount of players that actually used it,” a Blizzard CM said on the forums. “Trying to tackle and fix those issues (for transparency the majority were just exploits) just takes dev time away from working on new content. While it may change in the future, we currently at this time aren’t planning to bring this back.”
The CM said that the auction house itself is in need for some updates but that there are no plans right now for such improvements.
