Do we know they were actually Jedi? As opposed to being in-training, or at the very least very inexperienced…the Jedi slaughtered in the PT were battle-tested and even Masters. Big difference.
True. That’s a fair point, but what was Luke doing for the past 30 years? Yoda told him to pass on what he had learned…did other things take priority? Does it take 30 years to train new Jedi?
Evidently not, considering it appears Rey has learned pretty much on her own…in ten minutes.
Luke wasn’t exactly a Master. Doing and teaching are also two different skills. Perhaps Luke wasn’t a good teacher.
As far as Rey’s journey to the Force goes, Luke learned almost as quickly. Granted he had a bit of teaching from Obi-Wan, but not much.
