Legion launch was smooth, because a new technology called server sharding was implemented. Since the launch of 7.2, players have been experiencing lags and servers have been down several times for unexpected maintenance. After thorough investigation, Blizzard came to a conclusion that addons like World Quest Group Finder were the main cause, and in order to improve server stability, functionality of how addons can interact with Group Finder has changed.
The good news is that it’s just an additional confirmation box. CRZ and server-hopping were also discussed in the latest Live Developer Q/A.
Today, we’ve changed what addons can do when interacting with Group Finder, in order to address major performance issues with the game service for players— not just for those using these addons, but for others as well.
In order to alleviate those issues, we’ve recently applied a hotfix that changes how addons interact with the Group Finder. Players will now need to give a manual confirmation when an addon attempts to:
– List and delist a Group Finder group.
– Search for and request an invite to a Group Finder group.
Addons that are affected by these changes will need to be updated to comply with this new restriction. We understand that this is a relatively sudden change, but it was important to resolve the performance issues as quickly as possible.
Note: If you are not using an addon that modifies the Group Finder feature, you should not encounter any issues resulting from this change.
