Baseball Playoff Format

I think that the 5 game format is a joke and have said so for years, a bunch of times on here.
Best of 7 is the only way to play it. Teams are built by GM's for 5 man rotations, its the only way to qualify for the playoffs. Then you completely switch the format to a 3-4 man rotation. Its just not right. If they wanna have 162 games and three rounds they should start the seaon one week earlier and play a best of 7 in each of the next two rounds.
