Ah I see what you are saying.I actually agree with a lot of what you're saying, but too many people seem to be missing my point, so I'm going to try this a more direct way.
I don't care how many Jedi were more powerful than Luke *before* the OT. I don't care how many Jedi become more powerful than Luke *after* the OT. What I do care about is the potentially more powerful Jedi existing *during* the OT... because THERE SHOULDN'T BE ANY.
Context: While Kenobi and Yoda are patiently waiting 20 years in exile for a new hope to help topple the Empire, Ezra is getting Jedi training. Prior to ANH, he's already gifted enough to completely control the minds of Imperial drivers/pilots and whisk away a star destroyer with his incredible force control of space whales. He also has enough self control to let go of his loved ones, thereby leaving himself less vulnerable to the dark side. Luke and Leia were born one day after Ezra, who had years of training under his belt before Luke first touched a lightsaber.
Question: If Luke ends up being as lucky or inferior as you're suggesting, and he never develops the type of Force mastery in the OT that Ezra clearly demonstrated in the years leading up to it, then how does the main protagonist plot of the OT make any sense?
Obi-Wan knows about Ezra. Yoda knows about Ezra. If you're saying that Luke isn't all that special, then why are he and Leia considered so important? Why would Kenobi not send Ezra to Yoda? If Ezra is better at learning the Force, he would've lifted that x-wing out of the swamp and even twirled it in midair just for giggles. And training Ezra to kill Vader would mean getting to avoid the whole "kill your own father" ambition that so many fans insist Yoda and Kenobi had in mind.
My objections to characters like Ezra and Ahsoka are all predicated on context and wanting to preserve the plot integrity of the OT. If I'm still not being clear about this, then I'll just give up.
Well lets get the obvious out of the way, SW had not had the benefit of any kind of expanded story at the time, so there will always be inconsistencies.
I always viewed it as they thought, or believed that Luke would become more powerful in the force than Vader, Palpatine says as much as well…..trouble is, he didnt. What he does have, and what most of them failed to realize, is a human connection to Vader. Obi and Yoda pretty much give up on him when he flat out says he cant kill his own father (Then the Emperor has already won!)
They viewed Luke as a tool, one that would become so powerful, as to physically beat Vader…..they never expected him to win with emotion, not power. Once again, the established Jedi failed.
Ezra was in hiding. Up to a certain point , Jarrus did’t want them exposing Ezra to dangers. They were supose to be hiding. The interesting take with Rebels is the surviving Jedi, wanted to hide , while the new younger generation Jedi (Ezra) wanted to fight and get back what was lost. Thats the crux of Ezra and Kanens story for most of the show.
In short, Yoda has been dead wrong about alot, probably more than any other Jedi.
I also always saw the Jedi whom survived as trying to rebuild a force that could compete with the modern Empire. Ironically, The Empire came back much faster in the form of the First Order…
