It got Crunch and Throat chop. The only "better dark move" in term of pure power Moon could resonably get (aka "not wicked blow") is Darkest lariat. Roaring moon got one of the best physical dark stab. It is a type problem, not a him problem. And 80BP 100% accuracy is still pretty decent. Sucker punch or Knock off would have been nice tho.Just the typing and bulk make it really good. Obviously lack of dark good moves is a problem but you're right, it's really decent.
