I would be shocked if generations of experienced Samurai considered moving out of the way as an "amazing skill"
That's funny, because if you can simply "move out of the way" of anything coming your way, I would call that pretty amazing.
Why don't all the other Sumo simply "move out of the way"? How does anyone ever win a Sumo match? Actually, why does anyone ever get hit at all, why don't they just "move out of the way"? If you could master this "move out of the way" thing (and it sounds pretty simple) you could be the best boxer in the world, or maybe even the best martial artist in the world...
Sound's like a gross oversimplification to me.
