My PvP group has been enjoying BFV, even with sometimes random teammates, voice comm and teamwork have gone pretty well.
Hopefully the coop PvE mode allows you to gain experience for the Tides of War unlocks, I noticed the next TWO of those both unlock new tanks... they are going to be pretty much mandatory to unlock, one would think.
There are few enough tank oriented maps that trying to do that in regular modes for EVERYONE is going to be a real pain, if not impossible.
