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.
