I always thought it would be a cool if someone created a public voice chat server for frontlines. From a central lobby give users the power to dynamically create password locked rooms, they could then broadcast the room name and password to their alliances ingame (Im pretty sure most of the major voice chat programs would support something like this). Im surprised nobodies tried, though I guess getting people to use it might be difficult, and probably inconvenient for ps4 users. Plus whoever operates it probably gonna be stuck shouldering operating costs - which may be kinda high. Still think it could work.

Having SE integrate voice chat would be awesome too, but somehow I cant see it happening (data costs and such). On the other hand I think wow did have it at one point, so its not unprecidented.
