Ahh but there's entirely different games for that sort of survival experience like The Long Dark; a beans only carefree collection mode for DayZ would basically be a completely different game without the threat and tension of other players.
The cries for OPEN PVE just sound a lot like "I WANT THIS PART OF THE OPEN EXPERIENCE, AND THIS PART, BUT NOT THIS, THIS, OR THAT. ME ME ME. It's alllllllllll about MEEEEEEEEEEEEEEE!"
Nope, its simply a suggestion to get an official version of what we already have with Mobius, but instead of a single player bieng the arbitrator, its FD. Perhaps with some mechanics behind it to enforce the no-PvP rule, whereas in Mobius its currently an honour system that relies on Mobius booting PvPers who sneak in to kill unsuspecting people.
As stated earlier, i don't think this is the right way for FD to go, but i'm not criticizing those who are in favour of it.
