You are saing that you would like for lower star players (under 4*) to train faster so they can catch up with the higher star players, instead of - Anything with 1* and 2* is instant kick-out of the team? Significantly faster.
Hm, although keep in mind that, for instance, players with 1*, 2* and 3* can be sold off on auction for lower level Clubs to buy, which is very beneficial as it further supplies their auction lists with players. I my self do this every time I have some players that I just couldn't bother with further training up.
Do correct me if I misunderstood you, Khris.
