>>48708879>BW is the only gen to punish overleveling with diminishing returns, which is a more proper way to encourage using different mons/training other team members.Fair. White was the first game that made me understand you could complete most of the dex as you go. Specially, N shows you by using the local Pokémon to battle you.
I would argue that Exp share isn’t a problem since it helps you complete the national dex faster. The real problem is the static gym level system.
You shouldn’t be able to over level. The game should automatically adjust battle levels based on the highest level in your party. Further, gym and league battles should limit your team to the number of Pokémon the opponent has or make all leaders have a full team.
