If Rise beats NRG, then they will be 2-3 in groups, and since optic and knights who are both 2-2 have to play each other there is guaranteed to be 2 teams tied for the 4th-5th spot. What is the tiebreaker format for challengers, is it who won the head to head or something else like map/round difference? If it's head to head tiebreaker and optic lose vs knights, rise make it out which would be pretty insane considering how much better optic have looked as a team.
