How can this game not have built in voice chat?

Considering the amount of abuse that some players cop from simple text chat, I shudder to even think of the kind of toxicity that comes with integrated voice chat.

Generally VC is far less toxic than text chat.
It also boils down to the community policing itself.
If someone is being a dick in VC kick him and let him know it isn't acceptable.

I've spent 100s of hours in the in game VC chat system in EQ2 and a lot of hours in the lotro one. I've never seen anyone abused in a group, ever. People had pretty much zero tolerance for it in groups and people learned quickly or played solo a lot.

It was also fairly common for people to opt out of joining chat, most of the time because they were in a different chat client with their guild. A lot of people would also connect but not have a mic connected so they could hear directions and asked questions in text.
