I do admit Weedle has a point regarding Alola's absence of a traditional league and that it means Ash will not lose a league this time since his main quest has been the Pokemon School, which doesn't have any league-related stuff to do with it.
Then there was the fact that if you discount the regression of Ash's placement in Unova, he did get progressively better with every league. If a league does happen in the 8th Gen region, hopefully the writers will have learned from the controversy of the Kalos League result, which unfortunately sealed Alain's fate for me as an invincible Gary Stu character that I want to hate so much which was a shame because he had potential but blew it.
