Madden 21 Franchise too easy & extremely unrealistic

I'm wondering how the superstar abilities and x-factors fit into playing with modified sliders?

I did not play franchise mode a lot in Madden 21 and stopped playing it since it is very easy on standard sliders on All Madden difficulty because 1) there are some plays that almost always work and 2) it is so easy to read the defense. frankly, I simply didn't think of changing the sliders back when I was playing franchise mode but did some trials now (after reading this thread) how the game works when modifying them. I guess it is much more difficult to complete passes if your QB throws the ball anywhere but close to your WR (it was a very weird feeling seeing that my QB is not able to complete a passing attempt for 5 yards after having completion rates of 95%+ all the time with my "pocket deadeye" 99 OVR Alex Smith in MUT :D), etc. but for me it would be more fun if the strategic aspect would be more important (i.e. the chess factor requiring that you use plays that work against the formation and play your opponent has chosen and the AI adjusts to what you are doing).

anyways, back to my question: I guess the positive effect of adjusting the sliders is eliminated as soon as some players have x-factors and abilities. for instance, having a Lamar Jackson with perfect accuracy (due to one of his abilities) on all throws on the run (even for 50+ yards, no matter in which direction Lamar was running when throwing the pass...) while another QB does not complete a single pass all game long, no matter how easy the passing attempts are. I guess that balancing the game (in its various difficulty and playstyle settings) became much more difficult when x-factors and abilities had been introduced. consider comparing  2 teams where one has a perfectly accurate QB and a perfectly catching WR, and the other has not (while both teams have the exact same players)....
