id say that kratos lvl 2 is much better and more effective, cause emmets lvl 2 is kinda slow. yes he has more range, but kratos can kill emmet b4 the *thingy* XD kills kratos.
so in the end, incase of a FFA kratos can get a triple kill with his eyes closed, but, emmet's lvl 2 has to be timed RIGHT! just to get a triple kill, but i have a combo into lvl 2 to make sure that id kill at least one opponent. ( > O , down or > triangle) it would take specific characters to escape that combo.
