The Teamfight Tactics Set 11 meta still needs work and the devs are ready, testing Patch 14.9 balance changes on the PBE servers.
Patch 14.9 is an important TFT Set 11 Inkborn Fables update, falling between the first two Tactician’s Cup tournaments. A B-patch for 14.8 improved some balance issues for the first Tactician’s Trials and Cup but there’s still room for improvement, like a Lissandra nerf. The 14.9 update will also include 20 new Artifacts and five Support items.
