At this point I'd prefer a format like the new football's Champions League. No groups, 3 pots of 4 teams and you play against a team from each pot, and a single ranking. Or they could have 4 pots of 3 teams, so 4 matches in the first round instead of 5 (old format) or 4 (new format). At least the quarter finals pairing would be less random.
Anyway, they wanted to avoid teams "choosing" their quarterfinals opponent in the last round but they gave a huge advantage to the 2 teams that play the very last match of the pool phase - they can potentially mix up the whole table at their liking with good calculations.
