IMO it's the exchange rates across that need changing the most. Certain materials are still only really available by sitting around waiting for USS's to spawn and I haven't read a comment yet by anyone that says they actually enjoy this activity. If the rates across were reasonable then we'd be able to choose the activity we like rather than being forced into crappy gameplay that no one wants to be doing. I really hope the new discovery mechanics bring a decent change to this area as it's driving me loopy.
