I know it's going to be random but a potential playoff draw could be

1 - SEN
8 - ACE

4 - NV
5 - GMB

3 - VS
6 - G2

2 - 100T
7 - VK

The numbers aren't actual rankings, but this helps bring a lot of story line

My memory might be hazy, but I think its "random". For example lets say 1st seed of NA get into group A, if the 1st seed of EMEA gets picked (as the 2 major regions) they would get pushed into group B.

All just a working concept that would make it more fun for rng to provide death groups and freebie groups

I wish they did something similar to league, by picking teams live through a physical random draw for group stages (and making sure no teams from same region go into the same group obv)
