Sorry guys, should have provided a little more info in my post rather than just the image, but unfortunately, I pinched the image and don't know! I was under the assumption that you needed to level both sub classes in the image, and that this was the most up to date information...

I know it's not much help, but at least the main class listed is definitely (and obviously) correct, so it's really not that much hassle to level up another class to 15 (only takes about an hour if you just chase hunting log targets)
