Open World is just that - open.
It's a huge sandbox where we can all do what like. Unfortunately, what some people seem to like doing is blowing up explorers. Sadly, annoying and downright nasty as that is, it IS part of an open world experience, and not something I think FDev needs to waste time 'policing' or 'perma-banning' offenders. If games companies perma-banned people for being d*cks , then only you and me would be left playing..and frankly, I'm not sure about you.
I'm afraid we have to suck it up, and factor in the chance of meeting an utter b*st*rd as part of the exploring experience, and either pack some guns and shields, or be ready to run a bit sharpish.
When I got to Sag A, I did the usual selfies, scans and wotnots, whilst spending the whole time on my backfoot, ready to skidaddle at the first sight of anything popping up on my radar...while I'm happy to say hello to other players out in the wilderness, if you pop your hardpoints at any time, be prepared for me to give you a damn good 'running away from'.
The option is there to play in groups (I can't believe no one has started a dedicated Sag A group yet), or solo - if you choose not to utilize those, then good on you, but be prepared to take the bad with the good...being an explorer does not give us the right to expect special treatment, or demand to be unkillable by others.
Personally, the next time I head to Sag A (and lets face it, it's a big galaxy and Sag A is really the only place these plonkers
know they can find us) I'm packing some big fat guns...
nah. not really, I'll be running away again.
