What happens when you are a team who has to play in the AL East or NLC or whatever division happens to be the tough division of the year?
The only way for this to be fair is to play everyone equally (which isn't possible without dramatically changing the number of games).
We could get rid of wins altogether, and just base who gets the trophy at the end of the year off WAR and xFIP.
In all seriousness, I just it's just sort of one of those things that's too bad. The main goal was balancing out the random interleague games that are sprinkled in the schedule, and making sure you play your divisional foes equally.
