Strategies
Some (maybe many or even most) times you manage to beat a team when you scrim him and play blue side, but then in league, ranked or if he scrims you you lose. So first and easier is to let you choose "Blue side and purple side strategy" so this lets you prepare much better against others.
Then I suppose you could make non-subs have just 1 of each but let subs have maybe like 5 of each at least.
