I would like to see criminal enterprise to be more profitable in ways that didn't result in innocent players' deaths, and at the same time, have meaningless ganking treated much more harshly. It would be great for actual piracy to be much more profitable vs npc's and players, as in the theft of goods by breaking hatches or threats(pvp). At the same time though, killing a player should force the killer to be treated like an actual murderer, where they are killed on site in any system with security and barred from entering non-anarchy stations. NPC security ships are embarassingly pathetic, but having to go on the lamb and only use anarchy systems to rearm/refuel (without scavenging for limpets or using wings with ships that have roles like a mechanic ship, refuel ship, etc).
It's neat to have actual gameplay where players are engaging in faction combat or bounty hunting each other or being pirates or even being raider/reaver style death riders... but it's not a good system if the criminals are only criminals because they are bored and the game doesn't punish them enough. Make criminal activity be extremely profitable and dangerous.
Criminal behavior should act like exploration. When going on an exploration trip, the player is gone for multiple sessions and completely changes the way they play during this time. Light criminal activity should be like this, having to hide out in fringe systems after a "score" and have the feeling of being on the lamb. As with career explorers who have massively focused and usually large ships going out into the black for sometimes months at a time, a career criminal should be used to flying under the radar in security spaces, using their own cartel wings for refueling and repairs or supplies to support their activities and going back to "pirate ports" (anarchy systems) to do any modifications/missions/etc.

R- Make the player kill bounty also make stations in systems with any security attack the ships. Think of it like this, the current system (even in beta) is as if I got out of my car with a license plate on camera and shot someone in the back of the head while he was at an atm, and then with a full apb on that vehicle and myself in effect, i just drive down to the local walmart to restock my ammo and buy a rifle with the dead man's money. Then i go outside, shoot someone driving by with the rifle, decide I don't like it and go back in to return it for a refund on my credit card.
