Hey Tacticians, welcome to the Teamfight Tactics patch 9.16B notes.
In true B-side fashion, this patch will be fairly light. The biggest change is to the in-game matchmaking system, which should prevent you from seeing the same opponent too often. This change will be an improvement on past versions, but we're still not completely happy with the system and we'll continue to tinker going forward. For gameplay, the meta is in a pretty good spot following the inclusion of our Hextech friends, and we're giving out a few small bumps to the outliers.
