Another thing, I don’t want Rey, Luke, Kylo, and Snoke to be the only force users (though I don’t want a million like in the PT - one or two more could do).
It’d be interesting if Finn becomes force sensitive as well, though I don’t really mind either way.
Well we also have the Knights of Ren which is a completely new faction of Dark Siders and there is still a possibility that some of Luke’s students survived or that he took some new students with him to train on Planet Ireland.
