Taekwondo

A korean modern (ie last 200 years) martial art created for military combat. Unfortunately the martial art has become so popular that it has suffered from a severe case of McDojos & huge increase of the sport version over the traditional art, 10 year old black-belts are far too common & the McDojos are everywhere. The sport version is split into two branches WTF & ITF where the latter allows boxing methods to be employed. Unfortunately the sport is nearly completely useless for self-defence due to its point-system emphasising high kicks over strategic attack, penalty on aggressiveness in combat & not allowing grappling/clinching which all other sport-arts allow on some level + in WTFs scenario restarts after contact. There is then the even worse branch ATA which is scam-artists at its best, ATA isn't recognised by the Koreans as a real branch of Taekwondo & ATA refuse to compete in ITF/WTF competitions alongside charging high prices for training. Traditional Taekwondo is like any other art, a complete system in all aspects with grappling/locks/takedowns & strikes + weapon combat. Unfortunately it is far & few between to come across, Taekwondo is a prime example of what can potentially happen when a martial art is turned into a sport, though this hasn't been the case for many sport-arts such as Judo which is a highly effective system adapted to many police forces.
