Dont quite agree with this due to following reasons:
1. Limiting a player to growing only 10% a season is very less.
2. In the first method , the player doesnt grow at all (or maybe i misunderstood) and all teams will be playing with exactly same players.

The main reason why I want this levels to be scraped is that I want to be able to play with different teams in league, Cup and CL every season.
Imagine fighting for a league with the many maestros in this forum.
Currently, its not possible because all of us didnt start the game in the same season.
But, with this change, it can be done.
