I want to reconfigure MLB as follows:

[Aquavit]

5. A FIFA-style arrangement would be ideal IMO!

One league of 30 teams. Each team plays a home-and-away series against every other team, and all games are played Friday-Saturday-Sunday. Each game is nine innings long, period, and a team gets 3 points of a win, 1 point for a tie, and 0 points for a loss. The team at the top of the standings wins the title, and ties are decided by run differential first and away runs second. The bottom five teams are automatically dropped to AAA (and the five best teams from AAA, AA, A+, and A are all moved up a league automatically), and the sixth-bottom team from each league has to play the sixth-top team from the next league down in a home-and-away relegation playoff. Oh, and in this format there would be no such thing as the designated hitter.
