I think you should better concentrate on fewer good routes rather than equally profitable routes for each damn station.
Couple of the recent updates/mod versions clearly showed that too big variety of routes and mining locations scatters the players throughout the sirius. Some say it's good.
But EH, WAKE UP! We have NOT that many people to fill up each and every system of this mod. This is NOT EVE!
1,5 years ago i barely could log the server in the evening time cause of it was full. I relate such activity drop primarily to the player "scattering" forced by your work. We all had good times with Alpha/Gamma raids, Dublin Gold Rush etc. Gameplay now is really BORING compared to the old one.
Please, take a look back! No need to blindly develop stuff just for the sake of it.
