Cool. How does rewording what I said make you right? It's almost like being faster and stronger can defeat technical mastery it something. Which is, incidentally what I said happened.
Because it's seems pretty unlikely that half-trained Leia's Force harmony would be enough to make Luke significantly faster, stronger etc. than DE Palpatine, significant enough to overcome his sabers advantage.
One would imagine he'd at least rival his technical skill to make that work.
Or one could imagine Luke is just that powerful. Because again, Luke, and Leia for that matter, are that powerful. Luke is obviously skilled, but he isn't as skilled as Sidious. Especially given that not long after, he's struggling with far lesser duelists. Also she only used Force Harmony for the WoL.
Luke raw skill was good enough for him to duel evenly with one of the most skilled duelist the galaxy have ever known in Darth Vader; logical inference should lead us to the conclusion that thanks to Luke insane intrinsic aptitude and incredible learning ability, that Luke's skill increased with experience battling various opponents (Lumiya, Flint, Nightsisters, Noghri, Ssi-ruuk, Shadowspawn, Luuke), etc.
Krayt may be a Vader level duelist. I don't take the whole Vader > Sidious BS seriously as I think he is at least a tier above everyone else in that era except Yoda and Luke being able to defeat him(even if it was a boosted feat) is still enough to put him above both Vader and Krayt as a duelist. I agree the all out fight here is arguable but sabers only should definitely go to Luke.
