I find difficult to believe that in the word of pokemon 1 year is enough to bring a team of 6 to champion level, not to mention that the mc don't even start with 6 pokemon and that means some pokemon have few months to reach that level
Don't worry about that, in particular what I'm looking for with this story is to maintain a certain margin of realism, in fact it's impossible for a team to reach champion level in one year but what I'm trying to show is that most of Trainer They stick to the idea of capturing everything and having more variety in their teams, therefore they do not dedicate all their attention to only 6 Pokémon, also the further you advance on the routes you will find stronger Pokémon in certain areas and the more strong Pokémon you defeat the more experience you will gain
