This thread is to discussion matchmaking and league play. To kick off the thread, I wanted to talk a bit about the current state of the matchmaker.
In a recent random sample of 100,000 matches, we found that in approximately 95% of matches, the difference between the average skill rating of each team was less than 50 points. The matchmaker is doing a good job in most cases. Things get more problematic at the very low and very high skill ratings. Our change to duo queue for 1600+ ranked players is part of our efforts to address this. In addition to that modification, we’re working on some fine tuning on the matchmaker. Our simulation with the proposed changes extended the favorable difference ratio mentioned above from 95% to over 99% of matches. I can’t give you specific dates on when these changes go live, but we’ll be looking to trial them on the unranked queue somewhat soon™.
One thing to keep in mind is that just because the average skill rating of each team is close, that doesn’t mean you won’t have a blowout match. Some maps just tend to snowball, some players tend to give up when they get a bit behind, etc. This can lead to a blowout even if the average skill rating of each team was fairly close.
