This is what really bugged me about M25. No matter how I tweaked the sliders, or whose slider set I used, I could not find a sweet spot in CFM.
For my defense, I either shut down CPU opponents pretty handily OR gave up a ton of yards and scores. On offense, I was able to tone down my run game, even lower than my team ratings would suggest I should get, but my passing game was only ever really stopped by interceptions, which came at a high rate.
I learned to be much more cautious with the throws I would attempt, but it was still a battle. If I toned down the INT's too much, then I could not otherwise be stopped by the defense, or I would reduce WR catching and see 8 drops per game. . .. it all killed the sim style I wanted to play.
I just want the game balance to be more like a real game if I play 15 minute quarters. Working with sliders, I can never get a real balance that does not create cheese one way or another, or tip the balance too far out for either the user or the CPU.
