If you're on PC, the various VC programs like Mumble and Teamspeak are better than any game built-in solution anyways.
If you're on PS3/PS4, there is built-in voice chat through PSN and you can use it if you want to, plus everyone owns a PC or smartphone so they can VC with their PC brethren anyways on their laptop or smartphone.

The game doesn't need VC built in, you're swimming in usable VC solutions if you like VC.
