There's a lot of negative sentiment around Genshin Impact these days, with players feeling like the game is stagnating with lame plot progression and the devs not listening to player feedback on how to improve the game. Wuthering Waves on the other hand had a rocky debut and many people wrote it off at the time as a failure, but it's now made a comeback with the game massively improving with subsequent patches and the devs listening closely to player feedback. A lot of Genshin influencers are actually switching to Wuthering Waves now because the game mechanics are far superior.
