Why not allow the sell of full set Blueprints for a tenth of the the goods that would be required to build?
As I power level my Arc i harvest a lor of Arc BPs, more then I need to continue leveling it.
I'll trade in sets of excess BPs for Future Era Goods. I'll sell those highly marketable Goods and have the proceeds funnel back iinto my Arc accelerating that power levelling and getting more BPs.
When I'm done with Arc I'll switch the donations to some other high Era GB i need moved uo. If I ever ran out of Arc Goods customers I can switch to power levelling some other desirable high Era GB and do the same thee. Then i could acquire and power level other GBs and do the same. No need for Goods production.
I just get everything I need from using my Arc. Not just FPs and Medals, but now Goods and even more FPs as well! Good ol' Arc.
Not bad for an EMA player, eh?
