I believe they made a change to rate limit people using addons as an attempt to make it faster for people who aren’t using auction addons.
The result is complete garbage. They’ve screwed over anyone who isn’t a botter in an attempt to stop the botters…
I’m not sitting there scanning the AH all day every day sniping auctions… why the hell are you punishing us because your in-game auction interface blows chunks? Who ever made this new rule should go into politics because they’d fit right in… screw everyone because of a few, this is the way.
