The generals that Bilibili Gaming used at this World Final:

– Bin: Jax, Rumble, Gnar, K'Sante
– Xun: Skarner, Wukong, Sejuani, Xin Zhao, Vi, Kindred
– Wei: Vi, Skarner
– Knight: Ahri, Sylas, Orianna, Jayce, Leblanc, Neekko, Yone, Galio, Smold, Syndra, Akali
– Elk: Kai'SA, Jhin, Miss Fortune, Xayah, Ezreal, Ashe, Varus, Ziggs
– On: Rell, Rakan, Alistar, Poppy, Leona, Nautilus, Renata Glasc, Neeko

The line on Bin is almost sure to choose Jax if the championship when this player has used the general to 8/15 games and only lost 1 game. Meanwhile, WEI junglers only play 3 games to the present, but if the championship, the possibility of this player will choose costumes. With Xun, this player has shown impressively with Kindred but Skarner is the general that this jungler uses the most.
The line between Knight has used up to 12 generals in this year's tournament, the most general user of the present time. Choosing a championship for Knight is very difficult, but this player is performing very well with Sylas and Akali.
Gunner Elk also uses up to 8 generals in this tournament, with the “cabinet” especially Kai'sa with 100% win rate after 5 games. Finally, support on use is mostly the generals fighting with the most popular options are Rell and Rakan, with Rakan is the preferred choice.
With very diverse options, it is difficult for BLG to choose a squad if you win the world championship. Even the players can choose other generals in the final and will make the choice even more difficult. However, everything can only be decided if Bin and his teammates can win the final on November 2 in London, England.
