Run 1: Makes it to HoT but down at him. Nox (IMO) is the strongest protag, but can't fight through the others plus Savage and Asajj.
Run 2: Tbh makes it to Malgus but finishes there. Her Force advantage over Maul and Malak is too easily abused, and with it being her best suit would definitely open with it. I've always held Nox above Dooku personally for the following reasons. While I'm not saying Nox has a way to beat Dooku at all, she is skilled with a saberstaff and could definitely hold off a saber assault long enough to either throw up a shield, blast him away, or do the latter followed by Force Shroud to regain distance before using her Force advantage. While it's not very large, it's noticeably present, and her darker/more advanced/powerful sorceries would surely down him. I don't see Dooku pulling any majorities here. With Malgus, I see him being a fight she can't win. FE Malgus is too much for her IMO. His ability to mix his Force use with his saber form is really impressive (not saying Dooku is lacking, just I'm more impressed with Malgus). His ability to choke out the Protags while still maintaining full focus on dueling another was really impressive for me, and I see him utilizing stuff like hurling items while engaged in melee combat and disorienting her and taking the win. Not ruling out the chance she'd pass, just it's more likely that she goes down. Against Starkiller I don't see her being able to handle his TK and would go down in a good fight after some redirections and such. Not sure if he'd figure out a way to keep her down, but after enough beating she'd run out of steam, likely before Starkiller but possibly after.
