Originally posted by PlacidityKylo had training and Rey had some training as well as combat experience.
*Potential* raw power in the force, not saber combat. While the force can enhance saber skills, said skills are mastered through training.Kylo had that excuse in his first film, he failed to demonstrate anything better in the new movie. All we see is him struggle with the guards, so that point doesn't stand at all.
Your examples are low-showings, which are countered by average/high-level showings, of which there are plenty more. Kylo has no such feats - consistently weak.
Also, no one in the upper echelon has had problems with non-force users in direct combat. This forum's dear Quan Clown believes Snoke/Kylo are in that group. We see Yoda casually TK the Emperor's guards, and Sidious toy with Maul and Savage.
He defeated Luke prior to the first film. He was also spiritually weakened, shot by a bowcaster prior to that fight.
No, he's consistently powerful. Defeated Luke, Poe Dameron, defeated Rey once, tag teamed Snoke's guards who are elite.
Yoda beat two guards who didn't attack and just aimed their weapons at Yoda. They aren't the same guards nor did they even attack. Entirely different situation with inferior numbers allied against him.
