As you may be aware, we recently made a change to Rated Battleground queues that makes players wait until the match has ended to queue for a new Rated Battleground, even if they had left that match. This change allowed us to close a loophole some were using to artificially inflate their ratings, but unfortunately quite a bit of abuse had already occurred by the time we implemented the fix. Our goal now is to restore as much integrity to the Rated Battleground ladders as possible, and we’ll be doing that in two key ways.

During our next maintenance we’ll be lowering all Rated Battleground personal and matchmaking ratings for those above 2200 down to 2200. The abuse was widespread to a point that many legitimate players’ ratings have been inflated just because they’ve played against those who had used the loophole to boost their rating, and so we need to get everyone back to some equal footing. But secondly we’ll be taking action against the accounts for those who knowingly and purposely abused the exploit to boost their rating, which will result in more than just their rating being reduced.

We’ll be keeping a close eye on things, and looking to take swift action for any further issues.
