I wouldn’t because I have no issue with Rey beating Kylo in TFA.
oh yeah i can completely understand that, i dont really have a problem with it either. However after watching the D23 tease and seeing the scene where Rey and Kylo are battling on the Death Star II it gave me the idea for this. in TFA (in this edit atleast) we would see Rey tap into the power of the saber and the force, but just barley. In TLJ we see in the Throne Room that Kylo and Rey are basically evenly matched after her training with Luke. So in doing that, in my opinion at least, when we see her battle Kylo in TROS it would show how much shes grown from Starkiller (as Kylo said “Shes only begging test her power”) to until now (She will have mastered her power)
