Voice Communication in Game

I'm sure I am not the first person to think of this, but why can't we have an in-game voice communication system similar to something such as what CS:GO has? After all the game is heavily team work based which requires communication.

I think that this would help a lot in DynamicQ as many times I am stuck in a team of all solos versus a 2,3,4 man, which puts us at a huge communication disadvantage. This wouldn't make the unfair match-up a fair one, but would give the team a fighting chance.

There is also the argument that voice chat could be potentially toxic or used to harass your team even more. But in my opinion voice chat would be far less toxic than the text chat. This is because I think that most people that are toxic are keyboard warriors, and wouldn't be as big once they got on the mic. And if someone is being toxic or maybe you just don't want to hear them, you could mute their voice just like you can mute their text currently.

I can only imagine voice chat helping the game more than it hurts it, and it makes me wonder why it hasn't been introduced yet.
