I've done the FvK a few times now and can not understand, for the life of me, why each side doesn't have it's own chat channel automatically ??? Yes I suppose one could create one and then tryb to find all the people on your side and invite them to it. But by the time you did that the session would be half over. Don't get me wrong; I like being able to talk to both sides in a map (and since it's just a multi-player online rpg with "massively" missing do to instanced size limitations, having it otherwise would make for small amounts to chat with). But being unable to plan strategy easily makes me hate the PvP in this game.
Perhaps seperated comms are already in the game but if it is, like SO much of this game information is, it's hidden, buried and, pardon the pun, cryptic.
