>>55144255Because paldeans aren't autistic and let their champions enjoy freedom without having to be stuck in the league for others to fight them (literally the reason Steven lost the title to Wallace, and probably the reason Red lost the title to Lance), the Top Champion serves as fifth Elite 4 member and gateway to the Champion title, it's not the position of the strongest trainer of the region (people think it coincidentaly does because Geeta is the strongest of all Champion ranks, but that's because Nemona hides her powerlevel)
Basically the Paldea League works like the Kanto League prior RGB or the Alola League prior SM, but rather than having to fight four trainers to become Champion, you fight five.
