So, Brazil, the team with the best campaign in the tournament, with 9 victories in 9 games, having only lost 3 sets, is rewarded not with any advantage, but only with disadvantages.
They have to leave Katowice, where they had been seeded to, they have to face two teams that finished 2nd in their respective groups, who also happen to be the best ranked teams remaining in the tournament, and finally they have to play the first two matches of this last group stage, while their opponents play the last match, an advantage for them, as they come into that game knowing exactly what they need to do, which also allows for some manipulation of the results.
This format makes absolutely no sense.
