good point. I think in reality though, you can never really prepare for an actual fight, especially for those who've never been in one. Even if we train how to disarm knives, guns, and fight from disadvantage areas, until it comes time to defend against actual opponenets for your LIFE!! it's hard to say.
BTW: it's called BMA Blended Martial Arts.. You can't mix martial arts techniques you can blend them
