In patch 5.1, we resolved some issues regarding how Addons interact with the Battleground queue system. It is no longer possible to automate queuing for standard or random Battlegrounds in groups larger than 5. We decided to make this change in order to improve the experience for all players who are queueing into random groups normally and expecting to face similarly random groups, only to find themselves crushed by a full team of coordinated opponents.

We understand that players want to enjoy coordinated team play, and we invite those players to queue into Rated Battlegrounds or play Wargames to have that experience. Players can continue to use Addons to queue for Rated Battlegrounds as well.
