Pretty much nailed it, especially the Second Coil feels like it tries to throw in a lot of mechanics just for the sake of overconvolution and some of them just happen because they do and sure they make sense and might be cake once you figure them out, but before that especially going in blind for the first time you just kind of have to guess why and when it happens by trail and error and doesn't really feel like it flows as naturally as other fights for lack of a better word to express it, you are indeed dancing way more around the mechanics than you're actually fighting the boss. There's a thin balance between what a boss does and what happens around it and I agree the dungeons and the first Coil get that balance right, while T5 onwards lean towards the weighted mechanics side, it's fine because they're all beatable and really not that hard when you know the dance, it just doesn't feel as fun as other fights in the game but hey some people like everything in the game regardless so props to them. He also nailed the part about statics and lockouts, shame it's another meanie mean post not praising the game, time to ignore it into the trash it goes, right.
