According to the New EU, there’s this weird line of Jedi that all realized the Jedi Order was super bad. Most of them end up leaving, through good or bad circumstances. A lot of the fandom is of the opinion that these guys are super based and the reason they’re the most important Jedi is because they recognized the Jedi were super evil and stuff. Which is really weird if you think about that idea even in the context of the PT, let alone the OT.
Yoda > Dooku > Qui-Gon > Obi-Wan > Anakin > Ahsoka, although maybe Yoda doesn’t count since he doesn’t fit as well. So Dooku > Qui-Gon > Obi-Wan > Anakin > Ahsoka?
The only ones who didn’t leave were Yoda and Obi-Wan, but even Obi-Wan was super critical of the Jedi according to the New EU.
I’m probably not expressing this idea very well
