The current flow of clearing World Quests in World of Warcraft is pretty straightforward. You see that there’s a world quest out there offering a reward you want, you head for it, you’ve got an hour left. You reach the location, then you find other people killing everything around you and not letting you get a hit in. Well, unless you were using World Quest Group Finder, which allowed you to auto-form and auto-join ongoing groups, ensuring that you were always in the right group to take on group or solo quests as you arrived.
You know where this is going. The addon’s functionality has been prevented with the latest update by Blizzard.
Lest you think this was a purely malicious act, the official rationale is that the addon was causing serious performance issues affecting everyone in the game, and by forcing manual prompts rather than automatically forming groups players will enjoy a smoother play experience. At the same time, it was a popular addon which shored up a major weakness in the world quest structure, so players are quite unhappy that it’s not working. The most recent update to the addon alters its functionality to still provide utility despite the changes, but it’s still going to require more work than just showing up and teaming up from here on out.
