The team mode should be changed to a difficulty level that can be challenged by a single player

My opinion is to change it to a difficulty level of 1-6, with solo or multiplayer team challenges;

For individuals who are weak individually, the purpose of teaming up should be to overcome insurmountable obstacles and bosses that are too difficult for a solo player; similar to how hunting in real life relies on cooperation.

For individuals who are strong individually and capable of conquering anything, the purpose of teaming up should be to improve efficiency.
