OK, the MLB should tweak their proposal, so that division winners wouldn't get seeding priority (ala NBA). This means that a division winner would potentially not be a team that chooses their first round opponent, but rather is among the chosen teams, as at least one wild card team is in the #2-3 seed range. And then you have the possibility of expanding to 32 teams and realigning into 8 4-team divisions (ala NFL). This means that the playoffs would have to expand to 16 teams (8 in each league) to preserve having four wild card teams in each league (because there would then be 4 division winners in each league). Again, if a wild card team has a good enough record, it would get a top 4 seed and the ability to choose their first-round opponent. The first round would remain single-elimination. A key reason why I'm proposing the removal of seeding priority for division winners is back in 2015, the three best teams in the NL were all from the Central. But Pittsburgh and the Cubs had to play the wild card game, and the Cubs, who won, had to play St. Louis in the NLDS rather than waiting for a potential NLCS matchup. Meanwhile, the Dodgers and Mets got to avoid playing an NL Central team until the NLCS, where the Mets eventually beat the Cubs (who won the World Series only a year later). The NBA has recognized the problems that come with seeding priority for division winners, and thus tweaked their playoff format twice after the move to a 6-division alignment. first by only guaranteeing a top 4 seed for division winners, then by removing that guarantee and division winners not even guaranteed a playoff spot (though in practice, all division winners in the NBA generally play well enough to make the playoffs). I'm also proposing re-seeding after the single-elimination round, to ensure the two best-remaining teams in each league get a shot to meet in the LCS.
