I don't know how to phrase this politely but what exactly is the point of Shukuchi? In the first place the surface you're on has to be at least as high as the surface you're moving to, and even then if it's even a centimeter higher, or if it's too far away you'll just end up on the ground. It has no special effect, and even if it did it can't be used during combat anyways.

I just don't understand why this skill even exists, it doesn't seem to accomplish anything that a good old-fashioned jump can't.
