>>51818200Assuming you're telling the truth, Cynthia is one fight in the entire game. In my experience, the rest of the game is how
>>51818126 describes.
I also played the game, and I would consistently get overleveled over the next Gym Leader by around 5 to 8 levels, just from catching wild Pokemon and battling trainers. In any pre-gen 8 game with EXP Share off, I would normally be 5 to 8 levels UNDER the Gym Leader, because I level my teams evenly. In BDSP, if a particular Pokemon was overleveled compared to the rest of my team, I didn't use them. I counted, and I used my starter in battle only 3 times between getting the 1st and 7th gym badges. Hell, I had to avoid the underground because catching the Platinum additions down there would just level my Pokemon even more.
The constant overabundance of EXP was just a constant nuisance that affected nearly every aspect of the core gameplay
