Cool dudes are appreciated. But people should be aware that not everyone speaks every language. So if someone is, lets say, looking for help, then writing in kyrillic letters is not as likely to be responded to as if it were in english. English is spoken by most players i would think and therefore should be the main language to be used in public chats in-game, as it is being asked by elysium staff already.
I will never be arsey, like you put it. If someone writes russian in public chat i will probably just ignore, with the feeling that it's a pity in the back of my mind that i can't understand what this player has to say.
Anyway, i am so thrilled right now for the release and let's crash the server tomorrow at the stress test
