It may be 'narrow', but I'm proposing something that doesn't fundamentally change how the BGS operates - Rubbernuke's proposal creates (to my eyes) a large amount of extra player state that feeds into the BGS. That would be a big shift for FD to work on. Maybe they will do something like that in 4.0, but in the meantime there are changes they could make to the BGS, almost qualifying as QOL changes, that I feel would make it feel more self-aware. I'm just suggesting a tweak, and FD will notice it or they won't. Probably won't, and that's fine.
The commodity market, meanwhile, is totally soulless, whereas missions are like stories where the faction actually interacts with you. Why not marry the two? Missions that ask you to buy from this commodity market and take to one of our others? Or a totally different idea, not mission-based: have the faction NPCs thank you when you make a delivery of something particularly important. Or sometimes suggest a bonus if you trade a certain commodity? But that's kind of off-topic.
