Theres really no perfect way to do it. If you just seed everyone by records, then the issue is devaluing the divisions. There is a reward for winning the division. If the teams were playing balanced schedules, I'd feel differently, but if you are playing close to half your games against teams in your division, it doesn't make sense to rate teams from different divisions solely on the basis of record. But I think unbalanced schedules are really stupid personally because there's no way around having to compare teams from different divisions based on their record, whether it be for the Wild card, or for seeding, HFA, etc. Also, I'd prefer a quick 3 game series between 2 WC teams to determine the WC instead of a 1 game. Baseball is just too flukey in a single game to let one game decide a "play in" series.
