My idea is to remove that attack where he can be spamming square and then quickly turn around mid-combo and hit square to attack whoever is behind him. I have rolled behind Kratos soooo many times to get out of his spam, only to have him hit me some more with ease. This is terrible because spamming goes unpunished if you manage to get behind him. His main problems to me are what I just mentioned, his speed, and his AP gain. Either make his attacks more punishable when they fail or lower his AP gain, it's that simple.
