I hope they won't rank 16 teams based on 3 group matches. Then the ranking is done based on set ratios which might end up very weird ranks. They should match group winners with runner-ups from pre-determined groups
Only bright side is, we will probably see Haak playing in world championship. It was a pity that one of the best players in the world was missing second biggest event of this sport
They seem to be following the format FIFA world Cup used do far, so it'll probably be A1 vs B2, B1vsA2 in the eightfinals, then the winners play in quarterfinals etc.
