I think it would be better to base it off something with a little more mobility, the samurai thing is cool. But what about the wandering samurai? The lone Ronin, no armor, more skill. (Think Rorouni Kenshin, Afro samurai or samurai jack kinda thing?) Focusing more on QuickDraw techniques. Increased movement speed, but the blink is combined with the slash giving a faster longer range cut, but imposing the blink cool down into the strike preventing spam.
