1. the quality of SOE voice comms have always been terrible
2. I doubt that SOE would have the flexibility of doing what I discussed here
What they most likely have is CR restricted channels.
what games like Planetside need is a quick, easy, on the fly, managable voice comms system that allows for proper command and control. The flexibility of the system I outlined is it allows for ANYONE to lead a squad or a platoon at anytime just by having 2-3 keys setup in TS in advance.
Here is a vid that gives some idea of how the system works (the guy doing it could make it even a little more simple by setting a hotkey to turn channel commander on and off rather than doing it via mouse but you get the gist)
