This game doesn't need more money. You can change the way and the reasons it's given to managers but you should NOT change the global amount.It's like BIG said : more money, more problems !
Giving extra merch for one player only, discourages managers from stacking 3-5 of them in one team and encourage teams to buy their own star, instead of being a mid-low table team having no reason to have a star.We see this problem in many D1s and D2s and so on.
