Well, I personally can't talk to people when I play. We already have everything covered in advanced teamchat anyways^^ Not to mention that a good teamplayer knows what to do in every situation without having to speak. Knowing your teammates', and flagcarrying enemy's health is enough. Perhaps it could have a use in a game mode more based on level-knowledge, but still on teamplay - as assault? I still find it unnecessary in CTF, not to mention teambattle =p
