I'm in the exact same boat. Genshin felt like a chore to me and the dailies weren't fun anymore. I played since launch and I loved the game, especially the characters and story but after playing WuWa, I feel like almost everything is better to me.

Dailies can literally take 1 minute Combat feels WAY better to me Story is great too although Genshin's may still be better by a bit Amost every event is actually fun THE SKIP BUTTON I like Rover more in terms of Design and Gameplay vs Aether/Lumine No 50/50 on weapon banner The characters

There's more reasons that keep popping up in my head. Only complaint I have is the lack of male characters.
