Should CAS kits add new animations?

Yes. CAS is more than clothes. Kits have the potential to add bite sized but meaningful bits of content to all their respective areas. CAS kits should be more expressive of that with hair, accessories, hats, jewelry, face/skin details, makeup, walk animations, and more beyond simply clothes.

Walk styles are just one example of a neglected feature of 4 that could be bolstered with kits.
