Again, missing the point. Intelligent people tend to have discussions. Now there are a few of those who like to speak to each other while waiting for their turn to play. That discussion is hard to follow if you are having it in a chat window where some guys burst in and start speaking in their own language. Now I'm not against Russians or anyone else, but let them have a place where they can talk in their own language without disturbing the others. Said language channels would be justified by the number of Russian and Spanish/Portuguese speaking players.
Before you say "but you can whisper" no, I can't whisper in a way that resembles the main chat.
