All they need to do is make 1-5 systems open only with reward incentintives to battle. Attribute yourself to a superpower, and depending on what station, installation, and system it controls, all players across the galaxy pledged to that superpower gets bonuses.
This then gives natural, meaningful combat and will lure many of the gankers (that just want some pvp), tho not all, to it. This you will have at least less ganking, and the pvp crowd will have gameplay. But fdev idiotically won't do it even tho it should be very easy to implement.
1-5 neighboring systems in a galaxy of billions.
