Yeah - there are games for which I will use voice activation, like PUBG (where I do not have the mental availability to hit a PTT key), but for Overwatch I started with PTT with one of the thumb buttons on my mouse and I still do it.
That said, I use a for-realsies dynamic microphone with tons of off-axis rejection and a wall-mounted arm (I play games in my office/recording space, that's the engineer station mic). So I probably could use voice detection and be fine. But habits die hard.
