Well, i think this "new" Disco economy is well balanced. I knew another examples of dynamic economy on other Freelancer Server. This kind of economy depends automatically on actually trades ingame, the prices rise up or decrease, if you fly to often one route. So we all can be glad to have stable prices with all commodities. Otherwise you have to explore new Traderoutes all the Time. For example, you could haul VIPS from New London to Farway in the Nomadsystem, this route was very popular, and so, Profit fell very quickly.
Dont whine about this new economy, separate rejoice that we dont have dynamic economy. I just wanna tell you, things could be worse. ;-)
