I know there was some hubub about their being a "hidden" 50/50 when it comes to 5* on the Standard banner, and how the weapon banner is a FTP trap, but straight up lying about drop rates? haven't heard that one
although I will say the fact that* 4* event character are harder to obtain that 5* event characters can be mad frustrating
@Tyaren@Camel with 2 thumbs Yeah Genshin is too big to do crazy like that, it's kinda hard to believe. There were mobile games that did that with data miners, but I don't buy the Genshin rumor one too much either.
