I've long thought the solution to this, which would put much more value on how a team performs over a 162-game marathon regular season, is to expand MLB to include 2 more teams (Nashville, Charlotte) shift both leagues to 4- four team divisions and then have those winners play best of 7 series in the divisional and LCS rounds.
NL East - Mets, Phillies, nationals, Piraes
NL South - Marlins, Braves. Cards. Nashville
NL Central - Brewers, Cubs, Reds, Rockies
NL West - Dodgers, Padres, Giants, Dbacks
AL East - Yankees, Red Sox, Orioles, Blue Jays
AL South - Rays, Charlotte, KC, Astros
AL Central - Twins, Tigers, Cleveland, White Sox
AL West - Rangers, Mariners, Angels, A's
3 wildcards on top of 3 division winners per league had made regular season success and playoff seeding meaningless with how random baseball in October can be.
