The animation and effects are pretty visceral, and that ult just looks awesome. The audio is really punchy too.
I do think it would be cool to have some of that intensity in Genshin. No need to make all of the combat like that but maybe punch it up from time to time with some characters or abilities.
Although there is something to be said for Genshin's more relaxed and graceful combat as well.
Phone number damage.
Honestly you should consider giving controller another shot cause touch controls clearly aren't doing it for you.
Probably don't jump straight into abyss with controller, give yourself some time to get adjusted first and I'm sure you'll do better.
I usually play controller and when I want to tryhard I play keyboard and mouse. Maybe you can do something like that too, take it easy with touch controls and only use controller for the tryhard stuff.
