All countries had their quotas slashed for the event, only 80% of the last 3 events averaged can be sent by each country (in the individual events). So strict countries like South Africa this meant reducing their already strict set teams. This has left a ridiculous level of competition, for ex. Malaysia and South Africa have the same team size in athletics. Any athlete from Malaysia would probably struggle to make South Africa's team for ex. India and Canada have the same almost (31 v 35), and majority of Indian athletes wouldn't even qualify for Canada's team.
Looking at the wrestling entries, there are only 5 in a lot of the women's categories and other events too have a small number of entries.
So note to the CGF: Instead of reducing the county's allocation, make a qualification system for each sport that allows a good number of entrants, like they did with weightlifting.
