Upvoted for honest answerBeep beep, beep... you didn't read my post and you don't know how pve missions work in SC.
You encounter these players less than 5% of your pve missions. It's not a dream, that's the reality because griefing in pve mission is a huge waste of time (hard to track players or huge waiting time for really few encounters so as you said "no fun in that").
These players are found around stations, space ports and specific places, not in pve mission.
Another fun fact is that pvp griefers have also a huge mark locating them in Stanton for all bounty hunters. So a griefer can only use a small % of his time griefing, he has to manage bounty hunters most of his time.
