I don't think it's only in china lol. I played some games like this and everyone's been fighting who's the best guild leader etc. there's some drama too like guild leaders are being shipped with each other and some guild leaders (our guild leader) quit because their crush didn't accept their love confession lmao.
haha noo we have it on eu too! there was such drama, blackmail with privat photos etc. it was even worse than every stupid manhwa, people goes crazy over leaders, esp when the leader is a male lol 70% of time we dgaf about game, we were having our drama with betrayal and all this idiotic typical manga trops (yeah we were stupid) ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
Is like this in china where people is crazy fan of their team leaders stuff like that where they all want attention and are a fainboy/fangirl
