We see things differently. For some reason you want to protect Co-Op players more than they feel the need for themselves. Games are enough of a magnet for griefers. You just seem intent at using the fear of Griefers to deny what would be a vast improvement for a great many. FD takes player contact hostage to PvP now, you want to take it hostage to the fear of griefers as well. That won't stand. A CO-Op mode is a logical extension of the current mode system.
You can offer what ever vote you like but, you can't box this argument into the griefers corner. Let them find their exploits, and let FD squash them or ignore them as they come. The call for an Open PvE mode is multifaceted. You can't use the chance of griefing to scare down a good idea. Griefers grief, there's nothing to be done about that, except if FD were to make a CO-Op mode, they could, at least, bust the griefers for their actions rather than have the dubious separation we have with Private Groups now.
I see things as someone who's been developing software professionally for twenty years, and has to think about how systems can be exploited, and how to defend against such exploits when programming systems.
You appear to see things as someone who wants an Open PvE mode right now, consequences be damned.
I'm not trying to scare, to pick problems with everything and offer no solution; which is why I thought of a solution to suicide ramming and posted it.
No, I don't think it's necessarily a good idea to introduce an OPvE mode, and I would rather see changes made to the security and bounty systems first, then see the effects of those changes examined, then further steps made.
But that's not what I'm trying to point out here. I'm trying to demonstrate a potential exploit and have offered a potential solution, from the viewpoint of a security-minded developer.
