Just from out of the blue based on previous internationally performances:
KR should get 4 spots,
LPL should get 4 spots
EU should remain at 3 spots
NA should deserve 1 spot, and yes, that spot should start in play ins.
I bet there are so many 4th and 5th seed KR and LPL teams that can knock out the NA #1 seed.
After this season, regions probably see that getting an NA team in your group is a huge blessing..
And yes, at this rate, eventually worlds will be 6 Korean teams, 1 LPL team, and 1 EU team, and ZERO NA teams competing at worlds..
