You keep bringing up that "one moron" when you refer to player-killers. Perhaps you should look in the mirror.
If you don't engineer your ship to have at least some defensive capabilities, open will continue to be a frustrating place for you.
New player-killer types will be able to wipe the floor with your ship in a matter of weeks if they use all of the tools available to them.
Just take the time to do about one third of the engineering that the average player-killer does, and you'll be good to go.
Until then, don't take your valuable stuff into populated areas. And if you just can't stand solo anymore, at least be vigilant... and be prepared to high-wake if you see anyone you didn't expect.
I have a 57 LY Anaconda that never sees open. It's like flying a paper mache spaceship.
I know very well how easy those are to kill, and I like to think that I'm not a moron.
One feature of ED's diversity has always been that if you don't want to participate in a particular aspect of the game, you don't have to and your game experience will not be diminished thereby. You CAN "make a living" without mining, without trading, without exploring or evading all combat. If how you like to play doesn't involve active BGS gaming, you don't have to do it. You don't need to do PP if you don;t like it etc etc etc... Whichever part of ED you don't like, you can always do something else and that won't hurt your game or anyone elses.
The argument that you have to do engineering to survive in open is an argument that engineering is broken, not that the block feature is. If you're correct and the block feature is pretty much the only workaround to flying in open with all its social aspects and avoiding the RNG grind of engineering, leave it alone.
