The 'core team' that automatically qualifies for the VNL is unfair since the Olympic selection system and world rankings are now attached to it. The majority of countries have had zero chance of competing from the start.
Perhaps, strictly speaking, they would have been caught by some Olympic regulation, which does not fit the spirit of the event in the first place.
At the very least, the continental champions should have been automatically incorporated into the final qualifying round.
The sport would be even more beautiful if the African and Middle Eastern teams were stronger and if the VNL opened up opportunities for the more talented teams. The trait potential is there, as can be seen from the Iranian men's team.
