I can only think of a couple uses for someone to cancel a CD attack. Like Clark, no good there. Iori, and Kyo have good specials(both of their qcf + A) give them good space and will punish jumpers.
You want to get good at KoF learn block strings, good pressure can lock someone down. Find frame traps to score counter hits. Develop a good high low mixup game, you don't want to use the same option over and over.
I don't mean to shit on your article, but I'm an observationalist and its what I see in high level play.
