Entitlement? Joy of causing grief?
It doesn't matter. I hold the devs liable for that kind of bad behaviour. It's them who shape the rules. And when the rules allow antisocial behaviour it's just bad game design.
Wow, I had no intention of triggering anger with my questions.^^ I won't blame the devs and would not criticize a "bad game design" because they already do a tremendous job at keeping ED running AND proposing new content. And also because the Solo mode does exist, so it suits me at the moment. Oh, and also because whatever you choose to change or improve in a system, there will always be people to search for every breach they can find and jump right into it with the only purpose of enjoying a selfish moment of happiness with no regard to the consequences.
I fly almost always in open but if I was in a pure long range exploration build I would either go into solo or make sure I was in a system where you never see anyone, and if I did get killed at the start of an exploration trip my rebuy would be low, I wouldn't lose any exploration data, and I would just take the rebuy and start again after having lost a few minutes of my time and that would be that, not a second thought.
By the way, I did DW2 and got ganked at Beagle Point while in the Fleetcom PG. I escaped the attempted gank because I did have some degree of protection, which I find useful for exploring anyway, just in case.
Well, I thought my first message in this topic was obvious, because this is precisely what I do: I play solo because I don't want to be destroyed every time I use ships which are not meant to resist to a fight.
Anyway, the only degree of protection I care to add on an exploration/traveller ship is a shield meant to protect me from unexpected bumps (usually on the ground, in which I tend to bump when I'm distracted^^). The more efficient your protection is, the less you can jump. When it comes to exploring/travelling, I really don't like having a jump cap lower than 60LY.
If you're leaving in Open, then you need to build accordingly.
You could set up your exploration build by dropping modules off at an outpost on the edge of the bubble - you'd have to be really unlucky to meet another player in a real backwater system.
So - build a shield strong enough to give you enough time to jump, then finish your explo build in an out of the way system.
Alternatively - don't use an explo build in open.
Well commander ethelred, in my 1500+h of playtime, this brilliant idea never ever crossed my mind. I really feel like a newborn to have never thought about it.

This is exactly the kind of situation I love when playing/socializing with other players: you always learn or discover something. This is also why I'd rather play on Open. But I still don't want to explode.^^
Maybe I'll try your idea though. When I'll have the time and the motivation to make the preparation.
Why should players who bought the game with the ability to play without other players be forced to play among other players?
Yup, agree with that too.
