ok so no one is really answering your idea so I will.. I like your idea. However, you wouldn't be able to change up your teams much throughout the season, right? You would have to keep at least 14 players the same but a lot of people buy/sell. Nordeus would lose money that way.

It would end up being similar to Champions League in real life. You buy a scout and he would be 'cup tied', meaning, not eligible to play in cups.
