So im going to give you the real answer on why a lot of people dont PVP. Based on a little bit of schooling I had and experience in this game.
*stuff*
I'll give you the reasons I don't PVP in this game despite the fact I have PVP'd in other games and enjoyed it just fine. Only bothering to post because you didn't mention them in your post.
1. PVP in this game appears to be intensely boring to me. The 'to me' is highlighted because it's a personal perspective but the time-to-kill which is created by shield engineering, plus resistance/heavy duty booster stacking, plus shield cell stacking plus the Guardian shield boosters is ridiculous. I get bored shooting shield cell spamming npcs and they don't have anything like the stacking potential that a properly built PVP ship can attain. Honestly, spending 10-15 minutes taking someone's shields down is the epitome of tedium to me. I've watched videos of fights like that and I'm just like 'how can anybody find this enjoyable?' I totally get that some people will love it and find the tactical challenge thrilling but it just leave me cold. If I'm having a fight I want it to be quick, nasty and brutal.
2. The fact that the fastest way to have a fight which is actually quick, nasty and brutal (for you lol) is to fly a ship built for anything other than PVP and end up getting involved in PVP.
3. The fact that in a game with about 20,000 populated systems the only way you're going to take off in your PVP ship (which you can't do much else in) and be guaranteed to actually find some PVP rather than just fly round like a derp all night is to go to places that you know players will be. So that's basically Jameson, or the current CG, only a hell of a lot of the players at those locations won't be there because they want to PVP. That means I either steam in and attack them anyway, or just give up. Trouble is the only reason I ever PVP in games to begin with is for an increased challenge and fighting players who are not in specialised combat ships and who don't particularly want to fight me isn't a challenge, so there's no sense of satisfaction regardless of the outcome. That leaves organised fights, only then we're basically into an informal arena set-up which really defeats the entire point of playing the game to begin with for me because it's not a MOBA, it's an open world space game.
That's it really - it just doesn't fit in with the things I would choose to do to have fun
in this game. Now don't get me wrong, all of the above
could be changed (although shield stacking in particular has only ever traveled in one direction since I started playing three years ago and it ain't downwards) but I don;t see any inclination from the developer to do that.
The game was never designed from the ground up to focus on PVP. I think FDev made a rod for their own back with the way they designed it to be honest because what they've basically done is taken the chess club kids and the kids who liked to sort out arguments with a punch up after school, stuck them in the same room with a bunch of chess sets and then wondered why when they came back an hour later some kids have chess pieces shoved up their nose and are crying in the corner. The trouble is, they've sold the game now for four years on the basis of it being PVP optional. No developer in their right mind is going to tell their player base with 2.5 million accounts sold that they're changing such a fundamental aspect of the game's premise, it would be commercial suicide.
I do think you'll get open-only Powerplay eventually. No mater what other changes may come though, I can't see any way on earth that the basic question of modes is going to be addressed any way other than that. There was perhaps a time that such a fundamental change could have been made, although to be honest when you look at the fact some kickstarter backers are still salty as hell about the fact there's no offline mode, even that is open to considerable debate.
Now though, four years after release? It's a pipe dream mate. Really it is. If you're honestly expecting there's even a 5% chance of it happening, I can only suggest you stop because down that path lies nothing but disappointment for you. They have never given even the slightest encouragement for people to believe otherwise.
