I don't think Kat vs. Emmett is so cut and dry. I was playing dabuz and it's more like a 6-4 Emmett thing. The turret < Kat's Side Square. Emmett can zone her out for a bit but one false slipup and Kathleen gets the AP burst. Also Kat has it waaay easier kill-wise whereas Emmett has to rely on his Level 3 or getting lucky with a Level 2 in the corner.
EDIT: Emmett zones Kratos out like a boss. And he can shotty him away. --- PSN -> Bluechacho
