Teamfight Tactics 11.15 B-Patch is live. These changes will heavily impact the current meta with nerfs to one of the most dominant team compositions right now - Miss Fortune and Cavaliers.
TFT Patch 11.15 saw a meta that was dominated by reroll comps. Popular units to three-star include many that are being nerfed in the B-patch: Hecarim, Irelia, Sejuani, Soraka, and Miss Fortune. Units such as Hecarim, Sejuani, and Irelia became unkillable tanks that could also kill your whole team
when itemized correctly.
TFT 11.15b B-Patch Changes
With the changes introduced in the 11.15 B-Patch, we can expect to see a shift in the meta. The two reroll comps that have been nerfed will be much less popular and significantly weaker, however, these comps may still be playable since they will likely be uncontested when you play them now. Look to play MF Cavs still if you find an early Miss Fortune with items ready like Spear of Shojin, or get an early upgraded Hecarim with Warmog's armor.
The biggest difference will likely be in that the meta will be more balanced now that Hecarim is no longer unkillable and Archangel's Staff was toned down. This means that AP units will no longer seek out this item and can use more varied AP items such as Rabadon's Deathcap. The nerf to Lucian should not dramatically change compositions that revolve around itemizing him as the main carry.
