Leona
Although she was not changed at all, Leona is free-falling in the Teamfight Tactics champion rankings. The biggest reason lies in the nerf to Poppy and the gradual disappearance of the Candyland composition from the meta. These 2 Vanguard units complemented each other too well, making them nearly invincible in the early game. With Poppy no longer being utilized, people have also stopped paying attention to Leona.
Perhaps Leona is now returning to her true role as a tank in the Cybernetic composition and is no longer overused in many other formations. It turns out that 125 armor is not as overpowering as we thought; once the composition and the Vanguard units themselves are nerfed, that huge number cannot save her.
Sona
Although the Rebel compositions are showing signs of a comeback, Sona is the unit that has seen the most significant decrease in power after the 10.10 patch. The change to the Celestial Blessing now healing only 8 energy instead of 10 means she can no longer continuously heal and provide mana to nearby allies, making compositions using Sona more susceptible to counters and significantly reducing their damage output.
Previously, Sona also received a relatively significant nerf to her skill, now only able to cleanse stuns instead of all effects, along with the nerf to Celestial Blessing in patch 10.10, causing Sona to become increasingly neglected. With so many factors surrounding her, who knows when Sona will be able to return and feature in a meta composition again.
Twisted Fate
Among the adjustments to 1-cost champions, Twisted Fate is the one most severely impacted. The essence of the Card Master is being an early game carry, and with the damage nerf, a drop in power is inevitable. Moreover, the Candyland composition, which relied heavily on Twisted Fate, has also seen a disastrous drop in strength, going from a top meta position to an average level.
Most likely, Twisted Fate will only be used as a support unit for the main carry, activating necessary combos like Chrono and Sorcerer from now until the end of the season. The chance of our Card Master becoming central again seems unlikely, as Riot has learned valuable lessons from patch 10.9.
Jhin
The Dark Cosmic artist has finally seen a drop in popularity after a long period of dominance due to a series of indirect nerfs. Finding the best supporting composition for Jhin to deal damage is perhaps harder than reaching the sky, as the traits and classes that support him have been heavily nerfed, especially Dark Cosmic after two consecutive power reductions.
Furthermore, the strong compositions in the current meta either level up to 3 stars very quickly or deal overwhelming damage at one point, leaving slow but steady damage dealers like Jhin with little chance of survival. Additionally, other carries that are of the same cost as Jhin, such as Kayle, Irelia, or even Vel’Koz, are much stronger with the same amount of items and more powerful accompanying compositions, leading to him being gradually abandoned.
