I think Genshin has more animation frames per "animation", but it's a way slower paced game too. And the transitions between different animations and stances are much more detailed in genshin, where in Honkai it just "flips".
Not really, like you said genshin is much slower as well, it's how like some animations in something like SF5 aren't truly appreciated until you slow it down a ton.
There's no doubt going to be some animation compression in honkai cause of the mobile focus, but it definitely doesn't just "flip":
Post Honkai looks like Xiao on speeds. Lots and lots of speeds.
Nah it's literally just DMC 4 with a tag team mechanic.
Honkai is definitely more flashy, but saying it "crushes" genshin in combat is a little dishonest. It only runs on 2 axes, because in the main game you cannot jump and the stages have no verticality for combat portions
I don't understand how it's dishonest, it's not like jumping in genshin does anything unless you happen to be high enough; you can't attack with a jump otherwise.
Genshin's combat is pretty much taking crimson impulse from 4 years ago, slowing it down, taking away the "witch time" and adding a jump button that isn't used 90% of the time.
The movesets are highly static for each character
And they aren't in genshin? You got one basic attack string, a charge attack, a skill and a burst. Honkai has all of that depending on the character, even old ass white comet has a delayed input combo for variety. And as seen with more recent characters and old ones with a core upgrade, some get entire different movesets when activating the "burst" or charge.
but I feel that Genshin is the more refined game
Oh it definitely is, as it should be, would be weird if it wasn't, but I definitely can't say it feels "so outdated" unless I'm strictly talking about the graphics, which are obviously worse because of the platform differences.
