In terms of pure skill, Nightwing is above Deathstroke, yes. I will reveal R'as later; we've discussed that. When I say CQC, I literally only mean her raw skill in martial arts and combat. She would stand no chance against someone like Wonder Woman, obviously. However, her skill is enough to allow her to--at her peak--deal with others like Deathstroke (whom is stronger), Liam (same), Asura (with his speed) and even the Commander (whose abilities you don't know yet). Her skill is a huge gap ahead. It just hasn't been debuted because she is in her fallen grace period.
In an actual fight, Nightwing (Jessica Grayson), should be capable of defeating Deathstroke, Green Arrow, Red Arrow, Asura, the Commander, Scyliea, Karoline, Kal'Aya, Question, and a few others. Her skill makes up for her lack in strength--such is the disparity.
I'm a huge Nightwing fan despite being Marvel, so this is more a tribute to Dick Grayson being a badass in my eyes, but also because I want to make Jessica feel relevant beyond the being the next Grayson.
