Compared to what? And like you say, everything is limited. With the NHB events people base their opinion on fighting from results, how many schools are sying theoir art is the best but no one has ever fought? The techniques are too deadly? How do you know you can make them work. I have done the pressure point KO's on people who stand still for me, what are the odds of making them work in a real fight?So the UFC is limited then. Like everything.
In the NHB events they can say what will KO someon because they have done it, they know what will break an arm or legbecause some people did not tap and it happened.
Its easy to say you can overcome a grappler with an eye strike or knee them when they shoot in, but until you actually try it, its still theory.
