>>56535142The xp gain system uses a different formula, giving you less xp if you outlevel the opponent, and more if you underlevel them.
This doesn't really stop you entirely from being overleveled, and really just keeps you from being underleveled in my experience, but it does kinda tend to keep you <10 levels ahead and makes it harder to gain more than that. Assuming you're training a team of 6. Otherwise you're still overleveled. It doesn't make that much of a difference, but it's noticeable.
The game also gives you Lucky Egg as a handout though, along with Audino and shaking grass.
