These are ridiculous statements lol.
First point, no one cares that much to get that angry over something that is completely trivial. If he doesn't win, sure I'll be pissed, but I'll get over it lmao. No one is gonna be unhappy or rant.
Second point, Alain's characterization is leading up to something bigger. He's an experienced trainer, more so than Ash, he isn't going to be a pushover. He's not a favourite, he's a prop to introduce Team Flare and to make Lysandre appear as a protagonist.
Third point, I doubt it. Promos exist for a reason. The second part of Ash vs Alain is gonna feature a teaser for the Team Flare arc and then promos pick up the slack.
Fourth point, also doubtful. What will attract people to the Sun/Moon anime is the games.
Fifth point, perhaps your most ridiculous point lol. The games aren't going to suffer from the anime. XY/ORAS remain the first and third best selling 3DS games respectively and DP are the fourth best selling NDS games, so. That point is invalid.
Six point, no it's not.
