Because they think bgs is dull, and it is dull. Why expand to random system? Allow players choose system the faction expand to. Bgs has random effects, allow player factions players to control it, if their faction is rich enough allow players to upgrade station services or change economy. Allow player choose system state. War when they declare war against other faction, Famine when they are running low on food production, boom when they want to invest (factions money) to upgrade factions assets, investment when they want to build fleet of npc to protect their system or attack other system, lockdown when they want to limit services in system etc. Instead what now happens and system decide when each bgs state happens, give factions/systems resources like money, food, medicines, construction materials, troops, ships, population etc. and these bgs states would use some resources and produce other resources. For example you couldn't run boom for ever because your faction will go bankruptcy because you run out of money and can't pay for upkeep cost for stuff you build or keep navy and system security ships on patrol. Much more fun when every state has up and downside and change system and can have catastrophic effect on system, player groups could take risk, stay on war state longer or change to Famine so population doesn't starve too death and reduce the mineral production or cause npc faction revolution in system against your faction etc.
