Why Yoda *is* Great
Okay so I rewatched this video by Jensaarai and he literally has no idea what he's talking about. His main blunder is saying that because Yoda was not a creative duelist; he was inherently slave to form.

This is ridiculous. The same applies to Sidious. Oh wait, what's that? Sidious and Yoda are the only definitive 9's in the movie. Mace borders between 8 and 9, and Anakin is 9 when amped.
Clearly slave to form doesn't really matter when the two movie duelists who mastered all seven forms and didn't retool any form to make their own style (as far as we know) are the two best duelists in the saga. Therefore 'slave to form' matters not 😉
Also, his comments about the duel with Sidious. Jen says Yoda could have used Form II or Form III and not tired himself as quickly. Doubtful. Yoda was restricted to using Form IV offensively because his stature wouldn't allow him to use other forms for too long; or else his opponent would be able to take advantage of his small size and small blade.
Plus who cares? Yoda took the advantageous 'high ground' in a manner of speaking and using that disarmed Sidious. So it's not like he did poorly in that fight.
Jen states that Yoda trained himself to respond to the book. No creativity... while this isn't entirely false, it isn't entirely true either. Form VII was not wrote response. It required the practitioner to immerse themselves in the battle and enjoy it, and used randomised sequences and attacks. You can't just learn Juyo sequences.
Regardless, the two definitive 9's of the Star Wars saga are Sidious and Yoda, and both were textbook masters of all forms, neither really retooled any of the forms for their own use. They were just simply that good at lightsaber combat that they didn't need to.
