She comes off as a spoiled brat, that doesn't appreciate the Jedi Code or her training, IMO. I feel even Yoda would've slapped her in the face.
Who would your Ultimate Showdown be with?
I always felt like that was intended for Anakin, to give him some maturity by putting him in Obi-Wan's shoes (having a rebellious little jerk for an apprentice lol).
Hard to say who I'd want to face off against... I feel like there are plenty of Jedi Masters that would be fun to spar, but on the other hand, the Dark Side has plenty of good options too. I love the fights from the original movies, so Vader would be an awesome opponent, but I think Maul would bring an intensity that would provide an incredible challenge. That's only considering the movies... if we go to Legends, I'd love to spar against Grand Master Luke. For the SWTOR era, you have epic warriors like Satele Shan and Darth Marr who would be great opponents, but also some other favorites of mine like Lana Beniko.
If I went by your criteria, who I'd want to put in their place, I'd say AOTC Anakin. He's pretty unbearable lol
