Interesting. Never touched HI3 so I didn't know. I concede the remark, then.The spin/cartwheel dodge has been a thing for Mihoyo since Honkai Impact 3rd which they released in 2016. Nier Automata was released in 2017. So was the character switching system.
Genshin is a Honkai Impact 3rd that substitutes active fighter mechanics for elemental. Now whether HI3 copies an even earlier system is another matter, but it certainly wasn't Mihoyo copying Nier Automata.
There's evidently a lot of cross pollination in design and ideas between developers. As a consumer I just hope they continue incorporate what fans liked and improve upon what fans did not like, even if it was another studio making the mistake.
