So by your reasoning, you can only complain about something you find potentially unfair when you have a shot at winning the whole thing? A bit of a strange reasoning don't you think mate?
That being said, we all know how this works :
10. The tournament has a pool stage and an elimination stage. The winners and second place teams will progress from the groups to the quarter-finals after which all matches are played in a single elimination fashion.
11. Every victory in the pool stage will award your nation 3 points. Every draw in the pool stage will award your nation 1 point. (In the case of a draw points-wise individual round-difference will be used as a tie-breaker, and if round-difference would also result in a draw, 9 additional rounds will be played between the drawing nations.)
The most logical and fair system is that every team who toped their group face a team which finished 2nd in their group, but to clarify it should be written in the ruleset, just in case. That has already been discussed anyways. Something which should also be written is how you determine who face who but as long as its not written, then you can only assume its up to the administration discretion and its pointless to complain afterwards, next time check the rules properly or get your captain to do it.
Now to the adminstration itself, to avoid those kind of pointless discussions, you should maybe have planned it a bit before hand like Hekko did, hence announcing the seeding for the playoffs since the beginning, at the same time you announce the groups :
Exemple :
Spoiler
Group A 1st vs Group D 2nd
Group B 1st vs Group C 2nd
Group C 1st vs Group B 2nd
Group D 1st vs Group A 2nd
Just for future references. Oh and the OP could definetely use some updates.
In any case, looking forward to the playoffs, should be some good matches.
