I have to agree - Ash being the Alola champion just feels right. He has a strong bind with the region and the people, more so than with other regions.
…on the other hand, while it feels right, it only does so because JN, for all the flaws it has, hit the nail on the head with the Alola episodes. Especially 112 was brilliant and wouldn’t work as well if he became the Kalos League champion. However, the Alola league, at the end of the day, still feels like a mere school tournament instead of a proper league. I’m sorry, but no one had more than 3 Pokémon bar Kukui and James was in the QF ffs. It’s hard to take such a league serious.
