I don't love the genre but I have played The Circle, Arc Raiders and Marathon, plus the DMZ mode in CoD.
I don't think PvE modes are a good thing and don't remove issues with griefing or bad behaviour.
Arc Raiders for example was full of players waiting for a player with a key to come along so they could run in and grab loot from high value areas without any recourse.
The positive vibes and community feeling you get in Arc is because the risk is there of someone shooting you on site, but the bond of trust feels so much more impactful when you get along.
Obviously it's devastating when you get stabbed in the back, but to me it's like Dark Souls, Prepare to Die.
Getting jumped is an issue in PvP, but that can be tweaked with Time to Kill adjustments and better game awareness.
PvE just takes away the value of these encounters, or turns the game into a looter shooter?
