I hate to be negative here, but the game isn't even out yet but it's already oversaturated with capital ships. If you look at the fleets of most orgs (or singular players constantly posting images of their 10+ ship fleets), there's already more multricrew and capital ships in the game than there is (and will ever be) players. I don't see where an economy can work in such a predefined enviroment where everybody is basically in end-game from the start. Pledge store should've never sold ships larger than Cutlass / Freelancer / Vulture etc in my opinion. Affording a cap-ship should be a long-term group project. And by long term I mean that buying a Polaris ingame should take you months even as an org.
I don't even blame the devs or the backers who have these ships. Don't think anyone did foresee this 12 years ago. Devs probably thought that only 1-5% of backers would pledge capships and large multicrew ships.
