Or, for those who have in-game money, they could add something like buying perks (they can call them team building or whatever) that actually matter.
For like a million or two or five, you could buy perks for:
* Making 3 position training equal to 2 position training
* Limit CT effect to 33% drop of enthusiasm
* Reveal potential sublevels
* Making sure that a tight margin of 65-70 minutes results an improvement in GS
Things like these, that could add some depth in the game...
