The problem is their group stage only 8 team. Their open qualifier is so little team join.
If only they more open at the registration and invite more teams and make the group stage consist 16 team like any other SEA challenger it's not gonna be weird like this now.
you guys don't know anything but literally everyone can join, I believed like there's 20 teams that participated in a (non-live qualifier) it's just that only 4 teams are allowed to join the other 4 invited teams.
