Dare I say, "Make Credits great again", nice thing would be to allow users to purchase Mats.I really think hge shouldn't be the only place to reliably find grade 5 manufacturing materials. There really should be other ways to obtain these. Maybe they spawn on planet scan missions or inside compounds.
Maybe up the drop chance for pharmaceuticals in combat and add a few more grade 5s to the drop tables.
Maybe add the missing few to mission rewards.
I great way to interduce a credit sink?
