Combat zones should be made more exciting instead. Right now they're RES sites without asteroids and with lower pay per kill. One way to do this would be to considerably expand the scale of the fights by designing and introducing a few new subcapital classes for NPCs (frigates, etc) to be mobile and enrich the fights. Allow (or encourage) them to take place around stations and in asteroid fields. What's so special about a particular bit of empty space that there's a high intensity combat zone there?
The space battles should be occurring in strategically important locations. Space stations, rich asteroid fields, space elevators/skyhooks, shipyards (fighting amongst the ribs of an unfinished, half-alive Farragut? (and seriously, shipyards!)), orbital refineries...
I also hope to eventually see capital-sized civilian bulk freighters. Just more stuff. And I still think the demand for this could be met by contracting with content developers in the community.
