I think voice chat is essential for end game things and getting to know who is behind the text you see in ls chat every day. Communication is the most important part of end game, without it and you end up having a sub-par experience at best. It just adds so much to the overall gaming experience weather its end game things or a small group of friends chatting. If i had to give up voice chat then i would rather just go back to playing single player games on consoles.
