Krav Maga was created out of the necessity of keeping people alive, not as a form of martial arts. Of course, like all things it should evolve, and always strive to get better. However better dose not mean over complicating techniques and basically turning it into another martial art. It's foundation should always be based on aggression and principles over a specific choreographed set of techniques. Teaching someone only techniques without working properly on aggression will simply not work in reality. You'll have a dancer, not a fighter. Take care, Train smart, Sharir R, ICCS Head Instructor.
