I like to play in smaller leagues like Polish Ekstraklasa, and I finally want to see 2 improvments. Flexible league prize money, sponsors money, and TV revenue, along with risie or fall of league reputation. It's ridiculous, that my league is on 4th position by reputation, and still pay such small prize money and TV cash. I can handle it by suberb scouting, buying cheap and selling for much more, but AI clubs can't. They are always average, event if they have global reputation.
Second thing is newgen potential by nation, it also should by flexible or it should don't have any effect when your club has got best youth facilities, recruitment and junior coaching. When you pay such big money for junior coaching on best level after 20 seasons being club with global reputation, you shuld be able to rise some quality youth - it's just simple logic.
It may not be important for those that play with biggest clubs in biggest leagues, but in minor leagues it's huge problem after serval seasons.
