Yeah, any issues with the power of Rey are secondary to the larger issue of her place in the story, which I think in TLJ becomes a bit usurped by Luke.
Here’s my question though, I also have an issue with that scene in the movie, but how is your change fixing that? Not saying it doesn’t I’d just be curious to hear your thought process.
I’d like to hear the specifics of your issue with it.
As for my thought process, as I said above, her powers are well established and clearly equal to Kylo’s according to the saber breaking scene. It may seem a bit paradoxical to cure the issue of Luke’s limelight stealing sacrifice with even more evidence of his awesomeness, but the important thing is not the miraculous acts but how they relate to the characters. Luke knows that the First Order will see his power and glory on full display with his illusion. He must also know that if he helps Rey save the Resistance through the lifting of the rocks, she will get the glory and legend for this act though he had a hand in it. I see it as a final gift to Rey, a vindication of her belief in the legend of the Jedi which he passes on to her in this moment. Luke may feel that he is undeserving of his legend, yet in the end he faces evil regardless. He sees the value in such an act, and now Rey has the opportunity to feel what he feels; generating a legend greater than her own acts to become a spark of hope.
