As the title says, I think this game would be better if there's a language filter or some sort because I'm tired of having lobbies full of rude Chinese players who yell at me for talking in English.
Imagine this:
Players need to put their spoken language preference so that the English speaking players would be put on the same lobby as the other English speaking players and etc. If that worked, then both parties would have a better game immersion without language barriers.
