There could be ‘empire’ level pve content spanning sovereign space that simulates pvp strategic level warfare but to a lesser degree so that empires have to invest time to defend their systems from attack from all angles which should hopefully create an ISK sink (both in the fact there are no real rewards except salvage, no fonts of ISK from these attacks and they consume player stuff, requiring logistics and constant vigilance against these threats)
The lore rational could be that since the capsuleers who have renounced their loyalties to the empires have elected to rule their own petty kingdoms, CONCORD have decided to remove all bounties from destroying the pirate fleets besieging their structures and responding to capsuleers because CONCORD has no sympathy to those in sov space
I would fully expect the pirates who occupy ‘claimed’ territory to object to the presence of capsuleers pilfering their sites. There isn’t much dynamic to pve at present and largely null sec is only really the place of pvp. I think it’d be an interesting environment if we were more a presence in a world that exists rather than the stagnation that exists today with no real variation to how the game has been played over the last ten or so years.
