This doesnt seem like something you'd support as you dont seem to be for the rich getting richer way. And thats sure what this would lead to.
Au contraire. It would lead to every team being able to train and compete. Competition against 20,000 other teams instead of competition against the few at the top would not be the rich getting richer, would it? It would be 20,000 teams all with a shot at the top. I support that. I honestly think a lot of guys at the top understand that, and that understanding underlies their opposition to changing training.
Thought exercise:
Currently, what levels can you be competitive in and still train optimally? I'd say in V it's laughably easy, quite simple in a IV, somewhat challenging in a III, nearly impossible in a II and suicidal in I (and I've got experience actually doing that in all of those but I, and know enough about the NBBA from competing with those guys late in the Cup and in private leagues).
Your hypothetical lets *everyone* do that.
How much does a guy in V gain in your system? Nothing - except maybe instead of beating a bot by 50, they beat them by 75. Or not. How much does a guy in I gain? A massive benefit - because instead of having to replace entire starting lineups over time, they can use no-effort training to create three ideal players and then replace fewer players, thus removing some of the erosive effects that competition at the top levels causes.
Taking away literally the only advantage lower level teams have over higher level teams is pretty much a textbook definition of 'the rich getting richer'. It'd be different if it were reversed, and training was laughably easy in I and painful in IV - then, naturally, leveling the field would eliminate an inherent advantage of being at the top. But as always, I am impressed with how closely your knowledge about training matches up with your love for how it's implemented.
