TFT devs increase champion pool sizes for Set 12
Major changes to the Teamfight Tactics bag sizes are dropping through Set 12 Magic n’ Mayhem. Starting with TFT Set 12, the live balance team has adjusted the bag sizes of one, two, and three-cost Magic n’ Mayhem champions.
A champion pool, or bag size in TFT, determines how many one to five-cost champions are available to purchase from the shop during any lobby. This is especially important for Reroll comps and for players attempting to two-star a higher-cost champion when contested. The intent behind the change, Riot told Dot Esports, is to even out the power distribution between low-cost Reroll and fast Nine comps.
