Someone posted about verbal communication, but one of the problems was multi national servers, if verbal communication does come into play it would be more than helpful to have a mute function, or a "Do not disturb" feature also friendslist and even make group chats such as clan/tribe chats that you can work with. the communication now isn't top of the art but it gets the job done. and if multi national servers are a problem with verbal communication then i'd say just not to have them, have separate servers.
