It is broken. There is no NPC ship that stands a chance against a solo kitted out viper or cobra. There are numerous issues with the AI combat and NPC ship balancing. And the fact there is little difference between safe high security systems and lawless low security systems. FD have to be working on this - it cannot be as intended.
But they can't fix everything at once, I suppose. There has been quite a lot of dev feedback on this, so I am hopeful. It would be nice if combat were something to feel a sense of achievenent about. I know there are lots of different people with lots of different needs, time for the game, motor skills, hardware (I do find AI challenging on my old laptop at 16fps playing with mouse and keyboard...) - But, and this it the key, the galaxy is big enough to cater to all of us, with various systems of varying danger, but all the moment all of them are simply safe.
Now, given the amount of issues and balancing that clearly needs to be done, I would think it is low hanging fruit to have some systems be just really dangerous and others really safe and whatever in between. Maybe this is difficult for some reason I don't understand.
