I think they are too easy, but they need to stay accessable to young players. I think the addition of dificulty modes would help a lot, like the ones they tried in gen 5, but with more tweaks and improvements. Overall, smarter AI, items, extra mons, higher levels, coverage moves, etc. Of course, it should be avalible from the start instead of the key system. Aside from difficulty modes, there should be level scaling in open world games, like higher-level wild pokemon as you progress. Level scaling would also be cool for gym-like story points, so that in games like Scarlet and Violet, you can take on gyms/titans/star bosses in whatever order you want. Nuzlockes work pretty well for what we have now, but seeing more built-in challenges and difficulty modes could make the game more enjoyable for casual older players who might not know much about nuzlockes, or even long-time fans who want to play without rules about catching or healing!
