My idea, Simply remove the Away/Home part of baseball. Just have a single option to play baseball. When you play baseball, it would make your team play the other team once in your home field, and once in their home field. Winners still take some more for winning. This would effectively be a built-in 50-50 system, also it would allow for everyone to play with everyone else without really getting salty about leeching.
This is just my simple idea, if you disagree, tell me what you would like to change.
