With the next weekly Burning Crusade Classic reset in each region, all “pre-made” groups will again be allowed to queue for Battlegrounds.
After this hotfix, grouped players will primarily face opponents who queued in groups of similar sizes and the matchmaker will now match raid groups of 6 or more players against at least one group of 6 or more players.
If the total number of players in your raid is smaller than the maximum size of the Battleground, the matchmaker will automatically fill your side with other groups or individuals. If there are no large pre-mades in the queue, party groups of 5 or fewer players will be placed against other parties of 5 or fewer players.
Please note: Queuing alone or in small parties will not guarantee an opposing team with no large pre-mades.
