Obviously lightweight categories are completely retarded.
1) Height is an advantage in many sports. Should we also have lightweight basketball?
2) „Smaller nations“ have advantages in other sports (gymnastics, table tennis, diving, figure skating), should we also introduce heavyweight categories there?
3) There are way too many events in rowing anyways. If IOC wants to reduce the number of participants, they should have 3 events at most per gender. Rowing is very unpopular and barely anyone cares to watch, so it make the most sense to save costs by reducing the number of athletes in super fringe sports.
In general: More nations are able to win medals -> Bigger viewership
=> How do you (as federation/IOC) make the sport more accessible and how do you make the races less predictable?
