It was recently brought up how once a faction has max crystal storage, there's a flaw in the system. Not much to use the crystals on. And perhaps, you can't even get vouchers? Not sure about that one. So, what to do? Suggestions time!
-Convert the station quests from random economy items (Which I think has failed, I'm not sure anyone does these currently) to crystals. This would give a place to vent crystals after a faction's holding limits for them is reached. And get rid of all those damn random shops >.>
-Create a new npc that wants the crsytals for...reasons! Understanding that they're hard to come by, the npc lets people who turn in enough crystals borrow one of their wonderfully powerful items! Unique CrysTek equipment that boosts all sorts of useful things. Think artifacts, you borrow them for 24-48 hours, and then they are returned to the npc. Have system either be fairly expensive (100+) and they give you a list to pick from, or maybe a little cheaper (50+) and it's random each time. Or some mix of the two.
-CrysTek for guards! Power up factional guards using crystals. Because.
Please spew further thoughts, suggestions and feedback in a delightfully civil and respectful manner!
