It'll be so fucked
DRX vs PRX is not what we want first round, nor is Loud vs NRG or a EMEA vs FUT
Also fnatic could have an easier opponent than Team Liquid which is blasphemous for their seeding
I do not believe that is guaranteed. From my interpretation of the stated rules, each group stage qualified team will randomly draw for an opponent out of the four already in the playoffs. Teams from the same group will be on opposite sides of the bracket.
FNC has a lower seed than Liquid, but that only impacts map veto priority I believe. There are four "veto pools". Within each pool, map veto priority is determined by a coin flip, but group 1 gets prio over group 2 etc.
Group 1: LOUD/TL/PRX, Group 2: FNC, Group 3: EG/NRG, Group 4: lower bracket group qualified teams.
I don't know the link to the official rulebook, but I heard similar things from people who did read it. Here is what their public announcement said.
Those four teams will then be randomly placed into the double elimination bracket, where the top seeded teams have been waiting. Teams from the same group will be placed on opposite sides of the bracket to prevent a repeat match early in the winners bracket.
