Assuming if BYG win against FNC, DFM win against EG, and LLL win against CHF, there will be 5 3-2
how will the elimination bracket be formed?
https://www.youtube.com/watch?v=3E-iAI6rpnw tldr best gametime team (loud probably) gets first, rest form a 4 way single elim bracket seeded on gametime, winners of the first matches play each other for second and third place, for losers 4/5 place is decided by who has the best game time.
From the Rulebooks :
6.2.8. Five-way tie: If five Teams are tied at the end of the Play-in Stage, the Teams
will be seeded by Total Game Victory Time. The Team with the lowest Total
Game Victory Time will be awarded the highest seed within the tie. The
remaining four Teams will advance to a Best-of-1, single elimination bracket,
seeded by Total Game Victory Time (i.e. fastest Team will play against the
slowest Team). There will be no third place match completed, as per Rule
6.2.5.2.
