I agree with this in that the lower ranked pairs are literally there to make up numbers.
Australia (where I'm from) quite frankly - suck compared to Japan / China etc and it would be a very one sided match.
The only time where I was proven wrong, was the terrific WD match where Canada pushed the Japanese to 3 games.
However, if it weren't for the quotas that each country is allowed to have, it would be simply another World Tour event, just re-named the Olympics.
If not for the special qualification requirements, then every event will be class as a World Championship.
Even the World Cup (soccer) also operate in the same way as Olympics.
