Assassins
With two incredibly strong carries in Twitch and Talon, Assassins are currently one of the most effective rank-climbing compositions. Moreover, the presence of a strong single-target crowd control unit like Nocturne also aids Assassins in easily subduing the enemy team’s carry. Even in the late game, the Assassins team doesn’t lose strength, as Kha’Zix is a relatively strong and versatile 4-cost unit.

In the upcoming patch 12.5b, both carries, Twitch and Talon from the Assassins team, will receive damage nerfs. Especially Twitch, whose interaction rate with Attack Damage will always be at 125%, meaning this skill will no longer deal the overly “unrealistic” damage it did before. As for Talon, this nerf won’t be as severe as Twitch’s, but it will still make it more difficult for this unit to eliminate the opponent’s “tanky” units.
Elegant
Although not an overwhelmingly dominant composition, the Elegant VIP champions are showing significant superiority in the current meta. Additionally, players using the Elegant composition have numerous “counterplay” options based on the VIP champions they possess. You can push Brand, Syndra, Draven… to become the carry when their VIP versions are strong enough, helping players “blow away” the enemy composition or offering great damage or crowd control capabilities.

Therefore, in the upcoming patch 12.5b, key units of the Elegant team will all face relatively significant nerfs in terms of damage. This will considerably reduce the viability of using Syndra and Brand as carries in the Elegant composition, and players will rely more on finding VIP Draven in the late game. This nerf seems necessary from Riot to prevent VIP Elegant champions from being overwhelmingly dominant and controlling the game entirely as they currently do.
Gang
Following the update of patch 12.5, Gang has emerged as one of the strongest compositions in Teamfight Tactics. The buffs to Ashe, Braum, and numerous Gang units have made this team comp much more manageable in the early game and able to scale well over time. When facing a well-constructed Ashe – Gang composition, your carries will struggle to deal effective damage as Ashe’s skill also slows down the opponent’s attack speed.

Clearly, Riot cannot allow such a powerful composition to dominate for too long, so in the upcoming patch 12.5b, Ashe, Morgana, and Zyra will all receive nerfs to their damage or maximum energy. This change will noticeably reduce the crowd control capabilities of the Gang team, as Zyra and Morgana will find it difficult to cast their spells multiple times in combat. Additionally, Ashe’s reduced base damage will also leave this composition quite lacking in damage and prone to losing health in the mid-game.
