Personally speaking, I kind of like the idea that CCP is making heavily passive parts of the game more active. I think that this will create all new kinds of social dynamics and ways to play the game. That said, I feel that there will need to be an increase in the output of any given moon's overall yield per month, due to the high likelihood of harassment from external (and some internal) sources that will curtail the amount of moongoo successfully harvested and retrieved by the corp owning the refinery. This will encourage corps and alliances to find better ways to manage their moons and even create more PvE and PvP content, perhaps by baiting enemies with juicy mining barges.

In regards to what the moons will generate, I don't see much of a reason for the moons of nullsec and lowsec to change at all. It seems to have done well this far anyways. But when it comes to the moons of highsec and wormholes, I feel that there should be a different type of extracted item for players to collect to help keep the economy healthy, and still provide an opportunity for players in those systems to play with these features. I think that the old "Alloys and Compounds" could make a strong comeback in these areas. Obviously each moon should only be able to provide certain types of these items, and in different amounts depending on system stats. Of course these moons could also include more standard ores and ices, at the CCP's discretion.

But that's just my two cents.
