But that's the defensive set. What does it need speed for? So it can hit things with a 0 investment waterfall? Being able to wall things for longer duration is way better than having a negligible speed boost. I agree with weak armor being on the offensive sets, but defensive seems like it would be better suited for battle armor. Plus weak armor lowers kabutops' defense, that's not something you want on a wall. Not only does the defense drop contradict the entire point of that set, but it makes kabutops more vulnerable than it already is.
edit: my mistake
