Precisely, what are the standard poomsae rules for creative?
Perhaps it should be a compulsory part of the World Championship. It gives a more rounded perspective or a more "complete" competitor.
I think that's how gymnastics works to some extent. They aren't quite given a set routine, though they have to perform certain techniques within a routine. That can be like our standard patterns/poomsae.
Then they have their "creative" floor routine. Music accompanies the women performing. It's much more free flowing and shows off some "personality" for the individual. They still have set techniques – though I think they don't necessarily have to do them. If they want to score higher points, they still need to attempt numerous and varying level of difficulties of different techniques.
For our taekwondo creative poomsae, If they want to incorporate dance routines/moves/jiggling of body parts – then they should be allowed. Though they should be aware that it is not part of the score. Or maybe just a small part of the "visual spectacular" rather than the technical side of things.
