We attempted to play a multiplayer team game today to try out teamchat. Strangely, in those games chat jsut simply doesn't work. some people can see messages sent by others, others can't. You can hear the sound colonies make when someone sends a message, but you don't get anyones messages. I could see my teammates and no one elses, my teammate could see only mine, others could see some peoples messages from one team but not from their own and not vice-versa, it was just a mess. Even when I became an observer this was still the same. Ontop of that, I could not observe from anyones point of view once I was bought out.
In a FFA multiplayer game however none of these issues are present, except the inability to observe from anyones point of view. I assume that's a new UI bug though.
