we almost completed all required steps to finally have queues that are bigger than 2v2. The main roadblock was having an algorithm that can handle the premade teams of various sizes, that queue up, while still producing good matches. I wrote that algorithm over the last months and we tested it successfully in June. Recently we finally merged the code into the develop branch after making sure the code quality and test coverage was up to standards.
We are now testing new code that will handle the rating initalization for the new tmm rating. Once that has been merged we can make a server release to deploy the new code. Once that is in effect, the new matchmaking code will also be used for 2v2 matching. It is possible that there will be a short delay until we have added the new queues in the database. Once that is done, the new matchmaker queues will appear in the client. A client update is not required.
I will write a separate post about how the new matchmaker code works in the near future.
Of course we will also inform you when the update is in effect, but I guess you will notice that pretty soon if you regularly play matchmaker games.
