Forward square will catch people who are doing combos in FFA but it shouldn't work that well against experienced players and it can be punished if blocked.
Forward-Square was given to him to get him directly 'into' the battle. People who know how to play will use this to interrupt someones combo on another, and then use that time to attack the whole group now that they're all closeby. Keeping him at a distance is the best.
After you block the first two attacks, roll behind him. His 3rd attack whiffing will leave him terribly open.
If that kratos is smart, and he catches on, then he will do 2 attacks only. Let the mind games begin from there.
Jesus people, spend more time trying to figure stuff out instead of crying about how bad your getting owned.
The only things that need nerfing are his AP build, and the fact that he can switch which direction he's attacking BEFORE the last hit.
Otherwise, he has absolutely no long range game (lol bow and arrows) just run away and spam crap. If you have a melee character with reversals, use those.
Think about stuff man. Don't just take things the way they seem.
