I'm under the impression that a lot of people, including myself, prefer to play Solo mode all the time, not because we don't want to play with others, but simply because we don't want to PVP others.
same here, I don't like open play, because there are too many trolls / sad players who are only looking to ruin other players' day.
I'm in Mobius PvE group mostly, even tho you can still shoot others, group rules say that you're not allowed to shoot other players.
I'd play in open play a lot more if consequences of attacking non-wanted players, would be extremely severe. For example:
1. if you destroy non wanted player or cause damage to them, then you'd get charged for the damages you've done and you'd only have anonymous access in every station / base until you pay it off and money should go directly to another player, so they can use that money to repair the damage you did. If player has any cargo, bonds or other transactions pending, then attacking player would also be responsbile for all of those transactions. So if someone has like 100 mil worth of cartographics data, then attacker would have to pay that too.
2. on top of that, you'd get a "player only" bounty, which should be 50+ million depending on how much damage you've done and it would only disappear when someone collects it (it means you get destroyed by another player and not AI, so crashing your ship or letting AI destroy it, would not count).
3. when you have "player only" bounty, then you'd also have public bookmark set on your current ship, so entire playerbase would be able to see you and come after you.
4. when you logout, then your ship would stay where you logged out, so if you want to hit and run, then think again. your ship would stay, so others could destroy it and collect the bounty.
5. special options for powerplay, if you sign-up for powerplay, you should be able to select PvE only or PvP + PvE. If you have PvP, then players who are pledged to another power, wouldn't be punished for attacking you if your status is clean, but you're pledged with another power.
6. Ofcourse these measures should not count within conflict ones or if player has "wanted" status.
7. could also have "karma system", which means that if you're a troll / ganker and constantly cause problems for other players (who haven't commited any crime), then for example thargoids would make a note of this and chances of being victim to "random" thargoid attacks should increase.
8. Additionally there could be prison system, so that if you attack another player and then get destroyed yourself, you'd spawn in prison and you'd literally have to spend time in there (logging out would not count, you'd have to be active in-game, so leaving PC and going AFK wouldn't count either, you'd have to solve simple puzzles, such as typing in a code on keypad that is shown on monitor inside the prison cell). This would really make gankers think before taking a whack at innocent players.
These measures should only exist if someone attacks a NON WANTED player and causes damage to either their ship's hull or character's health. Accidents happen, so you shouldn't get punished if you accidentally bump into someone and only cause minor shield damage. You could make a proper system, that would detect trolls (like repeated shield damage would also count as attacking, some players just like to troll by taking one shot, then wait and do it again just to annoy others).
Right now punishment for attacking other players is just not severe enough, so there are lot of trolls and "gankers" as ED universe calls them and that's why I either play in Mobius PvE or solo. I think with such measures, nobody would dare attacking other players just because "it's fun".
I bet some ask, but what about if you want to be a pirate? Well I just answer with another question "what if you want to be a murderer in real life?". If you want to fight other players, you should do this in conflict / combat zones or some special events. Attacking players who are just minding their own business is just lame.
