WC is weapon’s based (butterfly knife) actions. You only need to touch ur opponent to end a knife fight you don’t need power. WC hand techniques r only for mostly stationary opponent in close quarter just short of wrestling. Both are flawed assumptions in a real life fist fight. WC is useful for a limited use case, a nice to have for a complete martial artist, not a must have.
Try that with a non-compliant partner, and hit to target rather than stopping short. Make sure you both have mouth guards, and wearing MMA gloves to soften the impact.
