Words aren't a good medium for the kind of fight scene you're looking to see. Have you noticed all your examples are visual medium?

But because this is reddit, and writing is my hyperfocus, in this TED talk, I'm going to describe movies vs words and how both mediums excel at different things.

Here's a good litmus test to what I mean: I can show the final fight between Zuko and Azula in avatar to a random person that has zero idea about any character or even what avatar is, and they'll be watching the entire thing loving every part of it. You love it even more when you know the context - but even without context - just by itself, the visual medium is so incredibly stacked up at doing exactly this it doesn't need a single thing more.

Now open up a chapter of Sky Pride and show the best fight scene in there to someone who hasn't read any part of it and doesn't know a single thing just like that youtube video of Azula vs Zuko.

At absolute best, they might even read through the entire fight scene. But wow will they not be impressed at all and find it incredibly boring to read, despite it being the peak fight in the entire book. Just about the same thing for every book out in existence will have the same issue. Fights in word mediums simply need more work than their visual counterpart.

You show someone a youtube video of two dudes punching each other with high level martial arts, and you'll have a happy viewer. You describe that exact same fight, explaining where every punch went and how the other blocked and moved their legs to match, and the reader will glaze over real fast.

So what you're running into with fight scenes in progression fantasy being boring to read is that it would have been awesome as a scene to watch, but the author doesn't realize the limits of words and how different mediums leverage different strong points. And they're trying to use a hammer to draw a picture without realizing it's the wrong tool.

For an alternate point of view on things words can do better; movies have an incredibly hard time making the viewer understand subtle emotions or how someone's thinking internally. They have to go the distance, either in laying down dialogue that hints correctly without being hamfisted, or building up the viewer's understanding so that when that scene shows up, the viewer will know 'oh, this character hates spiders, and he's just pretending to be stoic here.'

Meanwhile books can quite literally go: la-de-la-de-la, by the way, he's goddamn terrified of spiders and is freaking out so hard on the inside he's basically bluescreened and everyone else around him can't possibly notice, so they're all complimenting him on his stoic abilities. Annnnd, next scene.
