Blizzard announced on their official forums earlier today that they have decided to enable same-faction battlegrounds in The Burning Crusade Classic for the remainder of its existence.
Community Manager Kaivax stated:
Along with scheduled weekly maintenance in each region, we’re re-enabling same-faction Battlegrounds. A same-faction Battleground will now occur when an opposite-faction match cannot be made after a short time. We currently intend for this system to be in place for the rest of Burning Crusade Classic.
We’re also re-enabling the setting that restricts premade Battleground groups to a maximum of 5 players. We expect this to be a temporary measure. We’re investigating our options, and we’ll let you know more in the future about what our long-term plans are for pre-made Battleground groups.
Thank you very much!
Much like everything else in WoW, the reaction has been both positive and negative. Some have praised this decision since it will lower queue times while others have said this is due to a faction imbalance across several servers.
