Something I randomly realised and found kind of funny is how little Hoyo cares about quest spoilers in their official promo material compared to some of the other live service games (not just gachas) I've played
I can't imagine it's because they think everyone follows leaks since that's 100% not the case, but I still find it funny how brazen they are when it comes to essentially just showing people what's happening in the patch. I think during the 5.5 livestream they also freely showed the inside of the volcano and the red glowing area at the very bottom where it looks like you've stepped into a completely different dimension
I guess it's a tough market where they need to advertise everything, but I still found it funny none the less
