Having to rely on 3rd party tools for communication is a problem at times. Players use different programs to play the game such as skype, teamSpeak 3, Ventrilo and even free ones such as mumble. Keep in mind that some people prefer some programs more than the others for many reasons. So having one built in voice chat would not be such a bad idea. maybe even for a fee, they are charging a small fee for extra retainers I personally would use my money for Voice Chat over another retainer anytime.
