The advent of the elements in Teamfight Tactics has turned our well-established comfort upside down with its new mechanics, new champions, origins, and classes. It is therefore quite naturally that Riot Games deactivated the ranked queue with the arrival of the 9.22 patch. The goal being to give enough time to the players to discover the set 2 but also to avoid that smart little ones take advantage of certain flaws or bugs to climb the ladder in a few days.
So you have two weeks to train as never before and be ready for the return of the ranked games that will arrive just after the end of season 9, on November 20, the day of the deployment of patch 9.23.
