People passively win games with tremendous teamwork without the use of mics, full fledged clans who do work together and know what they are doing would be right up there. When I do have my mic on it's hard to imagine that i'm gaining any spacial awareness that I don't already have, other than that it's pretend tactics when someone is pointing out the enemy....it's fun, but I usually turn my mic off. All of that is odd considering I had alot of help in the last build when people in my tank were spotting for me, maybe it's the map to big really I like to play ambush.

That depends on how much such and such infantry or vehicle is influencing a game and how well that communication gets across random people. If a tank is rolling around covering every objective, squawking over the mics from a random stranger about a location of a tank is relatively unreliable and you can go on a wild goose chase when everyone isn't using a mic relaying all the positions of the tank. I don't expect everyone to use a mic, in fact they are on default turned off. If someone really wants to have a teamwork style game then they can wait until the beta as this is not what we are here for, other than testing the mic functionality. Mics again are fun but I have a little more concentration when I don't have to manage with people I don't know and am not yet playing with a corporation I am experienced with.
