Assassin
Basically, the players participating in the TFT Worlds Season 6 are top players in the world. Therefore, they rarely make mistakes in positioning, observing opponents, or using counter items. Thus, relying on the Assassin composition to secure victories in the matches of TFT Worlds Season 6 is extremely risky. Clearly, in such a fierce tournament, there is no room for this kind of risk.

Furthermore, the gamers in this tournament have extensive experience with TFT and know exactly how to build the strongest team compositions at various stages of the match. If you play an Assassin team in the tournament, you cannot be sure to achieve a winning streak due to a high chance of encountering countering Guardian players. By the late game, the Assassin team also struggles against fully upgraded 4-5 cost carries, so this composition has no chance of appearing in the tournament.
Renata – Brawler
According to statistics, on the final day of TFT Worlds Season 6, no player used Renata in their final composition at all. The number of players activating the 4 Brawler trait was so small it could be counted on one hand. Simply put, the Renata – Brawler composition was almost completely ignored by players during the most intense matches of TFT Worlds Season 6.

Of course, this is still a strong composition, but in the tournament environment, its power level is significantly weaker compared to other compositions. Moreover, being hard-countered by hot units like Galio or Irelia is a major weakness for Renata. With Galio and Irelia always appearing in compositions that made it to the top 4 on Finals day, Renata finds it very difficult to have enough space and time to cast her spells multiple times and deal substantial damage.
Ashe – Gang
The main strength of the Ashe – Gang team lies in its incredible tenacity, thanks to a large amount of lifesteal. When this team can withstand fights longer than the opponent, the chances of victory naturally increase as key pieces like Ashe or Zyra can hold full attack items while still having significant lifesteal. However, this playstyle did not showcase its strength in the recent tournament as it was heavily countered by a series of strong backline access champions like Galio and Irelia mentioned above.

Moreover, Braum being an overly hot tank has inadvertently harmed the Gang team as players easily find themselves in situations where they can’t use this unit. Essentially, almost all compositions in the top 4 on the final day of TFT Worlds Season 6 utilized Braum. Therefore, you will face intense competition for Braum when playing the Gang team, and without this unit, the composition is likely to “fall apart” and be eliminated early.
