So, are you OK with the current Working Draft version with Weapon Focus by itself?
Yup. You think it needs anything else?
Yes on your suggested alignment.
And, yes, remove that comma.
What do you fancy for a base creature? A normal human seems right, but I don't mind much whichever class. Rogue or ranger maybe.
Makes sense. CR +1 looks good, too, by the way.
I'm not much good at LA, but it's probably ok. Shade's usually pretty good with LA.
