>>42534618There is literally nothing stopping you from taking advantage of the terrains the same way the gym leaders do. Hell, most of the terrains can be broken somehow, and the ones you can't can be overwritten with a terrain move. The only time the enemies have an advantage you don't is when they have mons above the current level cap or the notMegas, but those are usually just 1 mon boss fights so there's still no excuse for losing.
