Hey has anyone been able to voice chat with their team mates? I read somewhere that by default it is deactivated for the objectives but I'd still like to be able to call out to my team so they know what's up.

I've talked to a few random people
I played the whole day yesterday and only near the end of the day got some replys and stuck with those people for a few games

I voiced pvssyd with my whole team and it was a blast, only it was in Ranked I think which has voice and friendly fire turned on!
