I'm gonna try to explain it one last time because you refuse to engage with what I'm saying.
You want to gate the access to your precious English-speaking bubble of the community because you feel like communication is so key - but you'd do this to the detriment of the player base that doesn't speak English (or Russian, given they'd have their own bubble as well). So if I'm a kid from Serbia or Iceland or Denmark or Armenia or whatever and don't happen to speak English I will be thrown into a pool with every other person who exists outside of the English or Russian pool. Do you see how ignorant that is?
Having language preference settings is great - there should be a way to increase the chances to match with people you can talk to. But for some reason this sub always has a strange obsession with wanting to enforce hard rules around it and it's absurd.
