Been there , done so , and I don't claim it's useless , it's just that SOME moves are flashy and useless in real situation .. Plus , TKD is not the exact same thing as karate , and what karate style are we talking about ?? is it hard karate or soft karate ??? shotokan , goju ryu or kyokushinkai ( or whatever ) . Must specify . For instance TKD's roundhouse is slightly different than shotokan's roundhouse which is different than kyokushinkai's roundhouse .
