Also, top 3 among 4 team qualify is a nonsense (4/6 3rd qualified it's so weird), to me it could be interesting to have 3 pool of 8 team, with a doble (or triple) bracket system to emulate a swiss round (but materialised with a brackets to make it easier to follow). After 3 round you have :
- 3 Team in 3-0 (The 3 teams are qualified for quarterfinal)
- 9 teams in 2-1 (9 teams fight in a play-in game for the 5 remaining places, you can qualify directly the best one, or let play the best team in 1-2 with the 9 other)
- 9 teams in 1-2
- 3 teams in 0-3
So we keep 7 round maximum, and every group stage game matter
