I think I like the new system where each continent has their own competitions and send one team, meaning 6 teams. Rest of the spots are decided in world qualifications where European teams probably will most likely get all 6 spots as they deserved it for so long.
The current system makes sense neither economically nor socially as previous post explained it. Worst of all, these low quality matches make the sport less watchable.
Maybe Brazilian users are worried to see Brazil losing to a European team in quarters? I am sure majority of federations love the current system where they pass 3-4 teams easily and get some nice points which helps them to climb in world ranking. Harder the competition means risking their chance of losing a nice spot not only in OGs but also in world ranking.
I honestly doubt that Europe would get all six remaining spots, 3-4 of them probably, but there are a few Asian countries, and even Dominican Republic(They took Brazil to 5 sets) can pose threats to some of the European teams
