Posted this somewhere else sorry if it is badly explained
Many don't understand the similar draws but it as flaw of riots system alongside optic being upseted fpx underperforming due to sub
they want to avoid same group being on same side of the bracket, same with na1 and eu1
they also want the winners of the groups not face to face na1 or eu1 in the first match to reward winning the group
this means b2 and a1 aswell as a1 and b2 being pairs on each side of the bracket
they want to put a1 on the same side as eu1 as it contains na2 who are expected to win the group for the same reason b1 is bracketed near na
the only thing random is the placement of sea1 and sa1
the bracket will look like this
eu1 vs (group containing eu2) seed2
sea/sa1 vs (group containing na2) seed1
na1 vs (group containing na2) seed2
sea/sa1 vs (group containing na2) seed1
so it is random but the only aspect is a flip of a coin to determine prx and lev placement
