Come to think of it, the Jedi are kinda dicks, they prevented anakin becoming a master despite his obvious talented skills in saber combat and his power in the force.
Not to mention, lore wise they let mundi have relations with his family where as it would’ve been a kick out for anakin.
Lastly, the jedi were sorta arrogant for thinking that nothing was wrong or that they were perfect despite having literal counterarguments from rebellious masters, Qui Gonn being a good example of somebody smelling the bullshit that the jedi were involved in.
So my fellow sith lords and jedi knights, what say you?
Being a master isn’t just about skill, it’s also about wisdom and experience, perhaps even more than skill. It’s perfectly reasonable that they wouldn’t want to elevate him to that rank yet, given his behavior.
