t2 teams

i saw on twitter that EP and REBORN are back to vct,can someone explain the format going for this stage?

the top 4 VCL teams go to the champions play-ins (they play against the 3rd-6th seeds in both groups of VCT)
winners of play-ins go to playoffs and play against 1st-2nd place teams from VCT groups

top 2 from each group go straight to playoffs, after that the rest of the teams(even the 8th-12th teams for some reason) go to play-ins where 4 t2 teams will join them and battle for the last few spots in playoffs

Top two from 2 groups gets a buy in playoffs while other T1 team play 4 T2 team in a playin and top 4 qualify to playoffs where previous Top 4 are in

thanks to everyone for explaining
