Why? What's the point of the article?
The point of the article is pretty much how reaction time is important in fighting games. Also how variation of moves can throw off the opponent if a said move is not used in a set, and suddenly that move is used the opponent may have a hard time reacting to it simply because he never had to think about blocking it.
If you've played any fighting game for a long time it's easier to understand. It's sort of like Mount N Blade in terms of reaction and variation. Just a lot more "deeper" and technical.
