Longsword build

This is my current build for longsword but I was wondering if they're are better ones or a mix setup as i really don't know what to use! I do have primordial armor set and risen kushala as well which is what I'm really considering using. One or the other but I'm not sure so any tips? I'm using sacred sheathe instead of special sheathe since i am loving the fact that I can counter most attacks!.
