It’s better to play on your own than to auto battle Because you can spam your team and attack all at once and do more dps. In auto battle it’s a lot slower and only one Pokémon attacks. I’m already very far in the game. Keep leveling up your Pokémon and save your gems up to 3000 and hope you get 5 star Pokémon. You can do the same missions over and over for Pokémon xp and items needed to get new moves and break your level limit. This game is about grinding as of now. Also you can check the max stats of a Pokémon in the Pokédex before you decide to train that Pokémon over others.
