I think he only really needs FS besides a CoC growth that will happen anyway.
There are just so many abilities, where normal CoC reaches its limits, because just reacting to it, doesn't get the job done. There's a clearly pattern attached to it, cause it's no coincidence that those who are meant to be stand above the rest all have it: Luffy, Shanks, Kaido and the list likely will go on later.
