>>18654407Well, no, the tournaments also get to show you how Iris improves as a trainer, if at all, or to at least show her as a trainer. I don't like her character, but the tournaments still have some importance.
>>18654409Serena doesn't know what she wants to do, which is fine because she gets to explore her potions. Iris wanted to become "best trainer of x" and didn't really have any other aspect to her character. She rarely did anything of importance, outside of catching dragonite and perhaps getting it and excadrill to listen to her whiny voice.
