ignoring the vast differences in both character & background of the two leads.
So in other words, you don't want to give the female lead the same amount of time to develop like we did with Luke.
In order to make that claim you would have to have Luke be a character with the same personality & background.
It makes sense she wouldn't need the same aid as a whiny teen with no life experience.
-Good thing she's not instantly skilled at everything.
-I think aomeonw who has literally had to fight to survive has a chance
-Good thing she doesn't master the force then.
And you're still ignoring the point that Ren was not 100% in the fight mentally & physically.
If Anakin can pilot a podracer because of his force sensitivity, then Rey can fight because of hers.
And these movies have never been grounded in realism.
This is why she would need to train.
