So CCP are going to touch POSes to some extent this summer - as yet we don't know how. So, here is the first thing they should do in my opinion that would have a large and positive effect on the game:

When a POS runs out of fuel, a 48 hr timer starts to countdown, after which the tower unanchors.

Simple, effective, won't require much coding.

At present there are hundreds and hundreds of offline anchored POS towers littering high-sec, this is preventing new players in particular from setting up their own POSes. A rookie 2 man corp really isn't going to want to spend an entire weekend shooting at a large tower with cruisers, just so they can use the space, and they shouldn't have to.

Yes, I know all about the war dec system but the purpose of it should be to forceably remove other players from their territory, not so that you can remove the unused relics of people who no stopped playing the game years ago.

Furthermore, it would create a whole new profession in the game - "POS hunting". It could be super profitable to find an offline (and unanchored) tower surrounded by assembly arrays and labs. A player could make his fortune with a lucky find.

I can't see any drawback to this, it would make sense from a mechanics and lore perspective (would Concord really allow space to be commandeered but unused), it would be fair to new players and would help to maintain the concept of Eve as a game with consequences. It would also create some great stories and tears.

Make it happen CCP!
