That video was neat, but it looks entirely like underpowered archery. Was it really guns that made people not care about this kind of thing (fast archery on the run)? Or was it simply more powerful longbows that meant archers would shoot from further off?
On a related note, in this video he catches an arrow out of the air. But that air must have been moving relatively slowly. There was a Mythbusters years ago where they investigated the myth of ninjas catching arrows, and determined it was impossible based on the time it took for a martial arts master to close his hand (measured with a high-speed camera) vs the time it took for an arrow to pass through the air. But this was assuming longbows fired from a castle wall. Those arrows will be going significantly faster than the ones seen in this video.
