As far as I know, based on the comments here and looking to game summaries, only two countries used crunch. I'm pretty sure you assumed the same, so to say you didn't name a nation when it can only refer for two nations? come on, give us some more credit.
Furthermore, the fact your team qualified doesn't make you an objective bystander to the situation. You would benefit from a disqualification of stronger opponents from the competition. Although strongly disagree, I believe you when you say you think that's the fair thing to do. But please, don't claim that the fact you already qualified makes you indifferent to the question who else going to qualify as well.
TBH - I don't think that there is a solution that will be fair to everyone. But I feel the solution Marin suggested is actually fairly good. Yes, it's far from perfect and there are some issues, but I found it fair because the rules and settings will be known to everyone before it'll start - so everyone will start on level terms. No one will get hurt for miss interpreting the situation.
