Many EVE players have issue with capital proliferation, and miss the days when you can take a battleship armada and conquer nullsec, with the satisfaction of defense so long as you can form numbers. However now, if you lack capital fleets, you run the risk of being evicted by a bigger fish. I propose releasing a new ring of outer regions, doubling the total nullsec space, that have interesting effects similar to wormhole effects.
They can be static or random, however they should be impactful enough to change the dynamics of a small gang or large sub-cap fleet fight, and make things fresh and new. The nullsec mechanics remain the same, only difference is capital ships of all classes cannot be used. This allows for a small gang heaven for those who love sub-capitals, and because these regions are connected with wormholes that lead all across EVE, and by new gates at the edge of currently known nullsec, sub-capital alliances can form and invade regular nullsec at will. Now the large alliances have small gang content entering their space from highsec/lowsec, wormholes, and the new nullsec, allowing for lots of fun fights to be had.
