A hotfix has been applied with today's maintenance that should resolve the Rated Battleground matchmaking delays. It appears that this issue resulted from a bottleneck that could occur if a team at the front of the queue was particularly difficult to match, which slowed down matchmaking across the board.
Those who are still seeing longer queue times might be experiencing a different issue. We're currently investigating a situation where teams with a large spread in their group's ratings may have a harder time finding an appropriate match.
While those teams are no longer creating a bottleneck at this point, queues may still be lengthy for them. We're planning to resolve that with an upcoming hotfix.
