I like the idea of adding, or hinting, or whatever about the Dyad thing in TFA since it is later spelled out in TROS. I think it would also satisfy people to understand how she “powered up” so quickly in the movies. Much better explanation then JJ’s response in TFA that she “downloaded” all of Kylo
s training.

I am fine with rare abilities or rare things in Jedi, that’s fine. Since Palps himself said it’s such a rare thing which explains why we wouldn’t have seen it in the previous trilogies. A-Ok with that!

It would be better than what the TFA was alluding to of "Light and Dark Side users balance out.

Since, well, it invalidates the previous two trilogies. If there is supposed to be a so called “balance” of Dark and Light side users … then the Rule of Two is invalid if there were 1000s of Jedi before.

And yes, one can say “The total power of Dark and Light, not the number of users” but the movie did NOT imply that at all. It was really portrayed as an individual/person thing as shown in the movie.

I would really love the hint, or even mention of it in the first movie. Just something since it will be explained at the end.
