If you got rid of the wildcard (which we've already been discussing how there are too many playoff teams), you could play all conference matchups as home and home.
Round 1 on October 21-22 and October 24-27
Conference semifinals on Oct 31-Nov 3 and Nov 7-9
FIFA on Nov 10-18
Conference finals on Nov 21-24 and Nov 28-30
MLS Cup on Dec 6
Those are basically the 7 match days they have already scheduled. The FIFA break between the conf semis and conf finals would feel pretty natural I think.
It just eliminates the wild card. Round 1 could even be started a day or two later to give slightly more cushion after season end. This would all feel a lot more like football as the world knows it instead of MLS turned MLB.
Kudos for addressing the schedule and calendar issue, but Home and Home is the worst possible option for MLS playoffs. It is a solution to a problem that MLS playoffs don't have. Two game series originated in a precursor to UCL called the Mitropa Cup. They exist to give both teams home games and avoid home field advantage in a knockout cup where everyone is in theory equal and should have an equal chance at winning. That's literally why they were invented: allowing one team to have HFA based on a random draw was a problem to be solved. There was no group stage and seeding. It was all a draw. It has an ancillary benefit of making it easier for both fanbases to see the contest, but balancing HFA was the big reason. Otherwise, nobody would invent a multiple game series with an even number of games and then deal with fixing all the problems that format creates. Otherwise, odd game series are the only reasonable way to proceed.
Because when the 2-game series is not solving that problem - which doesn't exist in MLS playoffs - a 2 game series has nothing but downsides. First, first games turned into giant defensive slogs. So they invented away goals, but that led to too may second games rendered almost meaningless. Our first historic home playoff game against Toronto in 2016 was effectively over after 1 goal in minute 6. UEFA, AFC and CONMEBOL club tournaments have all recently done away with the AGR, but the first game snooze problem never went away.
Second, it is entirely unsatisfying to have a team win its final [sort-of] game but be eliminated (NYCFC 2017), because a game should be a game and the point should be to win, not count aggregates. I know there have been amazing 2 games H&H sets with amazing second game comebacks. On the whole, they offer more uncompetitive final games than any other format. Because every odd game series ends with a discrete contest that starts 0-0 and one (or both) teams faces a lose and go home scenario. They never end with a win and go home result.
Third, and repeating myself but thisis the most important factor, the 2 game series all but eliminates HFA, which should be obvious because that was the reason they were invented and each team literally has the same number of home games. I guess now with Group Stage and seeding UCL and other tournaments could decide they want HFA but they don't. And there's tradition and that's fine. They should do as they want. But none of that applies here. We
want HFA in MLS playoffs. Unless you yearn to make the MLS regular season even less meaningful, there's no excuse for wanting 2 game sets in MLS playoffs with no real home field advantage.
Honestly, even Europe knows the format is all too often a drama suck which is why they abandon it in the final and go single game neutral site.
As I've made clear many times, IDGAF how the rest of the world does things, but if it matters to you then let's get rid of the MLS playoffs, because almost nobody else does that and at least that wouldn't make winning MLS Cup even more random than it is. At most have just a 1 round Cup final: Expand to 36 teams, split the conference schedules, play everyone 2x, and have a single game championship between East and West.
