First off, love this game. My criticism is merely to lubricate enjoyment of this game. I've tried to get new people into this game and this issue has been a turn off.
I wish I could turn off the badgering dialogue without muting the voices. I've played enough to know most of the objectives and the stakes. It really turns me off when I'm being badgered constantly especially when I'm losing.
The mechanics of this game make sublimely stressful moments all by themselves. I don't need someone telling me I suck or need to do better to motivate me. It's a slap in the face and it's not doing anything but ruining an otherwise great experience.
