if

group A: NAVI 1st seed, NRG 2nd seed
and group b: DRX 1st seed, FUT 2nd seed

then:

Playoffs

Side 1:

(2nd playoffs seed) FNATIC vs NAVI/DRX (groups 1st seeds)

(1st playoffs seed) LOUD vs FUT/NRG (groups 2nd seeds)
...............................................................................

Side 2:

(2nd playoffs seed) PRX vs NAVI/DRX (groups 1st seeds)

(1st playoffs seed) TL vs FUT/NRG (groups 2nd seeds)

and NAVI and NRG cannot be on the same side and DRX and FUT can not be on the same side (based on format rules)

its weird to make 3 leagues but still one of the 3 winners still face the 1st seed winner of his group on the first match
