Ahsoka could at least give Nox a great fight in sabers given her warrior specialization and agility versus Nox' more static, limited dueling abilities, like she was able to superior duelists like Grievous and Pre Vizsla. Nox has the Force edge but then so did Ventress and that didn't stop Ahsoka from doing well against her, she's clearly a potent enough fighter to keep someone like Nox at bay and even take a few minority wins. Nox 6/10.
Nox and Hero could each take on Marek from TFU I or II solo and probably come out on top. He's definitely got the TK advantage but I'd argue that Nox has for better Force manipulation in general; as well as Hero (very arguably/roughly) having better Saber feats. I think he could beat them each one-on-one, Hero more easily, but still would go probably 50 50 for each. (Maybe 40 60 for Nox winning) Also wtf is this about Nox having shotty saber skills? She's got serious skill with dat saberstaff; plus Force Shroud. Ahsoka's got SHIT on Nox.
