Parlor tricks. These have little to nothing to do with martial skill. Remember, you fight as you train, and if you train to stand around while somebody takes whacks at you, guess what will happen...
What if the same guy can do the same things while in motion? What about if they can do the same thing in the ring? What if they feel unmoveable when preforming a technique and all of that energy is redirected into you?
Isn't that when it becomes interesting?
