I think you're wrong about the usage of CH. Remember the scene where Shanks appears to stop the war. Along with BH he uses CH to block Akainu's attack, as it is easily impplied by the fact that Coby gets immediately nocked out. So i think it is really handy when facing a very powerful opponent, i just can't grasp exactly how it works yet. Probably by boosting the person's abilities and reducing the opponent's.
