Problem is that Open PvP probably would be very much deserted, leaving no people to explode.
LOL I don't really think so. Open already has a population of predominantly PvE players who are perfectly capable of not getting blown up by every other random wannabe ganker because first, it's extremely easy by design and second, they actually know what they are doing. Even if they do get shot down somehow occasionally, they just shrug and go their merry way after a mutual 'gg', and probably the next time they will be even better as they simply have a normal mindset for a multiplayer game.
And ofc there are other PvE players who absolutely don't know what they are doing. These players are usually way more toxic than all the gankers in the world combined (and I know
a lot of gankers, even very good ones, not only that one random dude an average PvEer gets ganked by once in half a decade). I could insert a wallpaper here full of salty local and system messages sent by these people only because someone dared to interdict their precious pixels in Open, but I guess the forum rules would not allow it because of the swear words. Honestly, these people are simply not compatible with a multiplayer game of any kind.
Let me tell you a story of some emergent gameplay instead, one that happened to me a couple of weeks ago (which wouldn't have possibly happened in a PvE-only mode btw). I was flying around in Barnard's Star in my shieldless taxi Viper4 and I caught sight of a CMDR flying a Phantom with some multicannons and a seeker missile rack on it. He even happened to be a power play enemy, so he seemed to be the perfect target (no notoriety) to find out how my shieldless ship will work against missiles without silent running.
I was about to interdict the Phantom when another CMDR's Anaconda suddenly interdicted me. I could see a familiar squadron tag on it (a predominantly BGS and Power Play oriented group, mostly PvE players with a handful of lawful PvPers whom I had already known for some time because I helped them in Power Play PvP battles a couple of times, I even knew a few CMDR names from their discord), but I had never met that particular CMDR before so I just evaded the interdiction but dropped on his wake afterwards to see what he wanted. The Conda was still in there.
"Hey" I said.
"Hey" he replied. "Did I interdict you? This was the first time I've interdicted someone. I've always wanted to try but our squadron have a 'no gank' rule."
"Well, technically speaking, I evaded your interdiction, but you still saved that Phantom, well played, congrats."
"I know your name from our discord, and I know you're a ganker, will you attack me?"
"Should I? I'm more of a wingfighter and generally I don't tend to gank the members of your squadron anyway. Besides, it was you who attacked me, LOL."
"Just need to say I'm 9 years old."
"Nice. I'm more than 50, sadly."
"Can I 1v1 you?"
"Sure, why not. Dw, I'm gonna stop at shield drop."
He's a smart little gentleman. I helped him a little bit with engineering and the other day he came with me to shoot down a couple of Interceptors. Obviously he's still a noob since he's a relatively new player along with his father, they even got ganked once or twice but that absolutely never stopped them to fly in Open nearly 100% of the time according to my FL. They definitely wouldn't leave Open for a PvE-only mode.
Well, not everybody can handle the horror of Open like a 9-year-old I guess.
You can only speculate because most of the pvp players have left, been deleted or their voice has taken away, keeping an echo chamber forum.
This.
