In today’s update we’ve fixed an issue with the MMR awarded by team challenges. The intended behavior of team challenge tokens is to allow a party to play against a significantly more difficult opponent, and to adjust MMR by an amount relative to that difficulty using the normal MMR formula. However, an update we released fairly recently caused this calculation to overcorrect, resulting in players getting significantly more MMR for wins. We’ve started correcting the MMR and rank medals of accounts affected, but this process may take a day or two to complete.
In other ranked news, we are expecting to ship season two in the coming week or so. We will post more details as we get closer to ship.
