A zero to hero series with this mod is actually incredible. Since every stats matter, you really have to find the right players to fit your style of play. Unlike vanilla FIFA or even games like PES 2021/2020, you cannot easily beat very strong teams with a weak team so there is influx of progression. Even though as a football game, it might not be that great, as a video game, it's extremely fun and have tons of replayability. Every players plays differently, every team plays differently. Changing formation against certain teams will yield huge results. Against big teams, you just want to sit back, soak up the pressure and hit them on a counter instead of playing possession. The game forces you to make these decisions due to the difference in quality. Also positioning seems much more dynamic than the vanilla rigid positioning which brings live and diversity to the match. Add to the fact that CPU changing formation and tactics during the match brings even more diversity every match.
I suggest you guys to try out a series of building a 1 star team and putting them into the glories of first division. And make sure to have a career mode mod that disables all these silly attribute boost and player growth boost that vanilla career mode has and I bet you will enjoy it a ton.
