I hear you Bill, and in the name of fun, I too would like to have a place where I can more reliably get into a fight with some hardcore NPCs.
What if I told you... ...that I don't think HAZRESes are the right place for that?
HAZRESes break my immersion already, I hate them. For a start, why would any miner go somewhere they are GUARANTEED to meet a pirate who will want to kill them, armed only with mining lasers and without shields? Secondly, why would any pirate go to a HAZRES without a full wing of 6, when they should know that these are the number 1 hunting ground of PF bounty hunters? LAstly, in what Universe do the bandits outnumber the regular civilians by 10 to 1?
It's nuts and makes no sense.
Compromised Nav Beacons serve my immersion far better, but are also subject to the same hit n miss spawn rates.
There needs to be another way. My suggestion would be to leave HAZRESes as they are now, places where one can go for big mining profits at the risk of fairly constant attention from manageable bandits. Perhaps introduce some kind of new zone or no-go area where nefarious NPCs might congregate and even spawn in waves.
