Honestly, I like the way how it is. I prefer the line, "You’ll take both sabers to Exegol to be the line that’s removed. It plays out much better this way: “A thousand generations live in you now. We’ll always be with you… but this is your fight.”
I thought this was how the line was supposed to be changed, wasn’t it? I found it weird reading the OP as I remember it was the “take both sabers” line that was being cut, not “a thousand generations”.
