What I don't understand is what was mentioned before, which I had seen a while back, that I think a writer or something mentioned that if Ash won a league, the series would have no reason to go on. How does that make any sense? Isn't the league championship something that happens once a year? Having Ash defeat the Elite Four is something that makes Ash an actual champion of a region. But even if Ash were to defeat the Elite Four of a reigion, that's the thing, it's only one region. Kalos is the 6th region in the games so far, with Alola being #7. Even if Ash becomes champion of a region, there are still 5 (soon to be 6) regions where Ash isn't Champions.
Maybe I sound like a moron for thinking this would be possible, but I was hoping that Ash would win here, then Alola wouldn't be a 2+ year thing, since there aren't any gyms, and then maybe go back to a different region, see some of the new mechanics like Mega Evolution in, say, Hoenn, go back there and challenge the league there before heading on to the subsequent game's region. And at some point, maybe 10 years down the line, once Ash has finally become champion of each region, start challenging the Elite Four of each region and then maybe actually progress into becoming a Pokemon master. This is just getting unbearable.
The most annoying thing about all of this is that Ash's ultimate goal is to become a Pokemon master. That's what frustrates me so much about all of his losses. If his ultimate goal is to explore the world and meet and become friends with all sorts of people and Pokemon, then seeing him lose the league wouldn't be nearly as frustrating. The fact it feels like he's progressed so darn little since his adventure first started over 900 episodes ago is what kills me as a fan of this series.
