Hello everyone! As a note, this Wednesday’s maintenance included fixes in an effort to generate better, more balanced matches in ranked:
Previously, searching for a match as a pre-made team would utilize the sum of the ratings rather than the average. This resulted in the system creating imbalanced matches in the case where one team had a party of players and the other did not.
So far, the fix seems to have already improved the quality of ranked matches. That said, if you continue to see issues, please do let us know! =)
