It would basically mean 12 teams go to the main event and 12 teams go to play-in where 4 get thru and we get the same 16 teams bracket.
Play-in could look like this
3 groups of 4, double elim (4 days) where the first seed goes to main event (3 teams) and number 2 goes to wildcardround;
Single round robin between 3 teams (1 day) (4th team)
Or ilike this:
4 groups of 3 single round robin (4 days)
(This would allow a group of death tho)
It would only take up 4-5 days and could also be held online, from where the teams are bootcamping.
16 teams just isnt enough to represent the amount of regions, maybe for summer they do something like MSI where they only send one per region, to make it a bit less hectic, but otherwise I dont see why they shouldnt do 24 teams. Because china, south asia and ocenia arw abouz to join VCT, no matter where u take those spots off it hurts. U would have to give, korea, japan, brazil only one spot or take off spots from na and emea, or not even include china, SA and OCE
