I admit that I'm in the minority. I want four eight team divisions. 4 division winners, the next 4 best records make the playoffs from each "League".
I want the "World Champs" to earn their trophy.
I'm agnostic about dividing among divisions, would like to keep the traditional AL and NL teams remain in their leagues. Maybe going back to the pre 1961 days. There would be a couple issues, Atlanta comes to mind. The current Milwaukee club has been in place longer than it was in Seattle. Dodgers and Giants are staples, of course on the west coast.
Maybe just make the Athletics play all their games on the road considering how much they've moved
