Taekwondo Flaws

Taekwondo is only good for sport the style has too many tricks in it's kicks and their no where near being good for self-defense.  If you were to remove all of the unnecessary techniques their wouldn't be much left to use.  This style is one of two styles that are used in tournaments where the rules don't allow punches to the head...if they wear head gear then why not.

The flaw in a successful take-down like this one is that the person can hold you down and bite you and use pressure-points or allow a friend to attack while your down.
