To be honest, I think null would be more fun if the isk/resource gathering were mostly passive and players just needed to protect the isk generators from other players. Mining for instance, would more interesting if it was done by an anchorable mining structure. Make the mining structure drop a high value mining core, make the mining facilities show up on the map and you have a small gang objective. Instead of people zoning out to the sound of mining lasers, you form a defense fleet. If raiders overwhelm the defenders, it becomes a race to get the mining structures torn down before the attacking fleet gets to them.
