Cpu doesn't challenge with dribbles that's true. But it does now make full field runs with the ball if there is space, so that's an improvement. Keepers are overpowered? I think this issue might be due to playing on higher difficulties than Top Player. Same goes for overpowered defending. And yes the AI does cheat on difficulties higher than Professional. You're a modder, you know this already.
The game is honestly significantly better now that the AI doesn't score every chance they have it makes a massive difference to the enjoyability of the game. But it's not like Pes 2021 suddenly became a 10/10 game. It just got better from what it was. I would give it a solid 7/10 for now. Not great, but enjoyable with friends trying to win Master League.
