I don't have an issue with the current system, I love it because it gives me a chance to win against the First division teams in the Cup
Again, you enjoy the system because for the majority of your games you don't have to think about it. The only time you have to think about it is in cup games that are against decent opponents, which is a minority of the total games you play.
it helps me against managers that always play normal even if they are as twice as strong as the opponents
Either those strong teams have no choice but to play normal to stay competitive (where the temptation to mutual tie is hard to pass up) or they aren't very good managers. I assume you're referring to the former where you get the chance to pick off better teams in the cup, at no cost to you since you're in an easy division.
I don't think it's more important than player and tactical choices
In setting a your depth chart you have to keep in mind many things outside of just putting the best team out there and playing the strongest tactic. You must consider HCA, minutes for training and also enthusiasm. Those things drive what kind of team to put on the court and if you ignore any of them that will hurt you in the long run.
This is what I love about PL and B3 games, you don't have to think about training and enthusiasm. It's even better with the new defensive matchups, so you can spend more time on actual tactics, matchups, scouting, etc.
