I think I'm starting to see why my training partners tell me there's a world of difference between mma and actual fighting, even under a controlled environment like a cage. That, is a total bs rule and seems to skew the advantage towards grapplers. Shoot and fail, don't worry about paying for the failure, try again. I mean, I know there are other things you can do besides knee the guy in the head, but it just seems so natural particularly from a sprawled position.
