Could WoT add a Preferred Language option to MM?

Dakiras: The "preferred" language is English, but there's no rule against speaking in other people's native language. The most important and critical information can be conveyed through the in-game commands. If you're unable to understand what people are saying then it's really not worth getting hung up over. It can't be helped if you can't understand it, just like it can't be helped if someone doesn't speak English and can't understand it.   Splitting each country into matchmaking groups would just be counter-intuitive and is likely to cause more damage to the community as a whole.
