Even if F-Dev didn't want to put a shipyard for which there are pros and cons surely they should've recognised the CG effort and given the station EVERYTHING esle.
It was a good CG effort and a substantial amount of mining, but 2,812 participants is not that much compared with what other CGs have got.
Some of the CGs to establish Colonia got around 10,000 participants. (In Colonia, before neutron boosts and guardian FSD boosters and the intermediate stations made travel so much easier - so you can't just say "well, it was a long way away")
Some CGs in the bubble to set up stations there have got as high as 15,000 participants.
None of those stations got a full A-rated outfitting service either. None of them should have.
Colonia has had players working on improving it for almost
three years now and still doesn't have full A-rated outfitting - which is fair enough, because establishing a human settlement in the middle of nowhere without depending on the backing of established superpowers should take time and be a difficult and gradual process - we earned all the upgrades we did get, and we'll earn more later.
And you think you can show up, do a week's mining, and get a Shinrarta-class outfitting service 26,000LY from the nearest manufacturer of half that stuff (and 10,000 LY from the nearest manufacturer of the rest)? Be realistic there.
If you want to establish a proper human settlement in the Core? With factories and production chains and supply lines and everything else needed to produce high-quality equipment? Then go for it!
Once DW2 is done, gather at the station, make it your new home, and as the first settlers in Colonia did, raise a big demand to expand and develop it beyond a basic scientific outpost into a full settlement. You have advantages over Colonia - you're starting with a new and undamaged starport that already has a substantial service list, you have a higher NPC population right now to start running an economy than Colonia had for six months, you have Colonia much nearer to you than the bubble is to Colonia to bring additional supplies from. Just don't expect it to be quick, or all handed to you instantly for shooting a few rocks.
