Honestly, I think you are taking this conversation a tad bit too seriously. Nobody is saying the animations needs to be on par with professional choreography from a live-action movie. So take your own advice and "chill" a bit.
Aye, like I said, the animation will never be of the quality you see in a live-action choreography. However, you can bring all the attacks up to the standard that is already established in the game. Earlier I brought up attacks like Ravage and Vicious Slash. Compare those animations to that of Sundering Assault. That kind of quality is easily established. Even part of the ravage animation is really good, the first two cuts of it. It is only the last attack which is out of place. You can actually observe the animation and separate it into two sections; 1) where the blade rises, which clearly makes it look like the lightsaber is as heavy as a sledgehammer and the 2) where the lightsaber falls down and lands, again making the impression of a really heavy weapon, swung with full body weight behind it.
As to the laws of physics, they are the reason I don't like some of the game's animations and why I brought up the nature of the lightsabers, and why you would never swing it the way the characters in the game do. Unless your target somehow blocks the attack, the weapon would hit and pass right through the target, throwing you off balance and in worst case on your face, unless you pull it back. Either way, you will either be in a vulnerable and bad position right after the strike or you just wasted an enormous amount of energy into one swing. That's an incredibly inefficient way to do combat and something any sane martial artist would know not to do.
This is why I was making references to the movies, because you can clearly see a progression in the way lightsaber combat choreography evolves, starting from ep 4 to 6 and then leaping to ep 1 and finally to eps 2 and 3, where it now looks the way I had always imagined lightsaber combat works at a high level. Even looking at, deep, dark side character like darth maul, palpatine, count dooku, and anakin, who are clearly aggressive in their fighting styles, you will not see the kind of attacks that you see in this game, which essentially looks off balance and like your character was waving around with a land-drill.
Now ofc, for the uncounted time, I'm not saying the combat should look as cool as the movies. Many of the attacks look nice and believable. Just fixed the rest on that same level and I'd be content.
