With Buzzerbeater Madness showing that a swiss style tournament can be coded into this game, I felt it was time to revisit one of my common suggestion topics in the form of redrawing competition formats for the purpose of either making them fairer, fitting them into a shorter season, or both.
In regards to the B3, the solution would be to have a standardized 128 team bracket for the swiss phase. Since we have 62 leagues in the game right now after smaller nations got merged, it would make sense to change qualifying so that the spot from winning the cup gets transferred to the league runner up should one team do the league-cup double.
That means 124 teams (62 league, 62 cup), so the remaining 4 places could then be filled by the B3 and BBM tier 1 winners if not otherwise qualified, then the 2-4 highest ranked teams not otherwise qualified to fill out the 128 . Once this 128 team bracket is set, the B3 itself can adopt the exact same format as BBM right now: 7 round swiss, top 64 advance, neutral court all season.
That sets the cutoff for making the knockout round to 4-3 regardless of PD, much like how the cutoff in BBM is 6-1 with no PD to worry about. Ideally I'd make every competition including leagues and cups in this game effectively neutral court, but making group play in B3 neutral is a start as I have long argued against the nature of 'doom draws' in the competition, and BBM has shown that a solution exists.
