The server update today brought an adjustment to the matchmaking algorithm for the team queues.
The main goal was to enable people near the edges of the rating distribution to be matched with higher priority. This hopefully solves the problem that the very top and bottom players find it very hard or even impossible to find matches. At the same time we tried to further improve the quality of the resulting games with some other tweaks.
This means that the average difference between total ratings of the two teams in 4v4 should be about half of what we had previously. The rating differences between individual players should also be about half for most games. Very high level and low level games will probably not see much difference here. We should also be able to see more high level games.
This is all made possible with an average wait time increase of just 2-3 minutes.
We also lowered the matching timer to 90 seconds to make it less disheartening if you did not get matched in a round.
Speaking of matches, with the new algorithm it is expected that the number of waiting players will regularly exceed the number of theoretically required people for a game, sometimes by a lot. It is not a bug if nobody or just a few people get matched in such a situation! The algorithm requires a pool of people to be able to pick good matches. If the games possible with the current people are not good enough, the algorithm will wait for more people to show up, and if that doesn't happen it will reduce the quality threshold by a bit for those that are already waiting.
When there are many people in the queue that means that there will be low wait times, so don't be discouraged even if you don't get matched immediately.
Please leave feedback below. I am especially interested if the situation improved for high rated players.
