Its good that you learn good skills. Good skills acquired through hands on trial and error. But what are hand to hand combat skills? Well its about seeing all the possibilities of reaching an opponent's pressure points first before they reach yours, and controlling them.
In a way its like rehearsing the alphabet without ever putting much of sentences but perhaps some fiction and definitely never putting a realistic story. Even in hand to hand combat training system the sparring has to be modified. But instead of getting control over the opponent in a knock out, or painful verge of limb detachment, or passing out, the instant prioritization of ability to reach the most available pressure point sufficient to lead the fight in the chain of defense and from there be always in control to one's fate it what counts.
