Pokemon: Let's Go Pikachu/Eevee makes a notable change to Gyms

Pokemon: Let's Go Pikachu/Eevee is going to make a change to how gyms work. If you want to take on a gym leader, you’ll need to clear requirements detailed at the entrance. This includes Pokemon types, levels, and more. For example, if you want to face Brock, you'll need to have a water or grass type Pokemon in your party to even get the chance.
