Because Genshin is a buzzword nobody will remember in a year, just like SWTOR, GW2 etc etc so I hate to talk about other dead projects.
For this game to succeed in the future they must have their own way of doing things. We can argue that modern players are fed up conversation because they have Discord, Twitch w/e but the point is, WoW was created for other kind of people and likely still lives today because he took another approach in doing MMOs. I do personally appreciate the fact that we can casually play this game without interacting with people nowadays, but major activities such as raids, pvp are requiring people to communicate. Sure most of modern kids use Discord for that, but there is a whole lot of players who don't and so there is nothing to do for them in the game.
