You ever wonder why you don't hear stories about scrappy groups from NPC 0.0 trying to take sov space and getting smacked down by the blocs who attempt to defend their territory? In theory this should happen all the time. In practice, it almost never does.
There's a 'You must be this high to ride' bar in front of sov null. Unless you are a bloc or are backed explicitly or implicitly by a bloc you're not going to get to get a slice of sov - and supercapitals are entirely to blame.
Whoever has the biggest supercapital group near a quadrant can ensure that an organization trying to gain entrance into sov null or build up any real capital fleet in NPC 0.0 gets utterly splattered. You want to try to build up a capital group in lowsec? Good luck deploying against a tower without someone in a bloc finding out and dropping a pile of bored supercarrier pilots on you. You want to build up or buy enough supers that you can take down sov structures without seriously questioning your life choices? You need to have more than a bloc can destroy to prevent them dropping on you - which means you essentially must be a bloc already.
I agree with everything written in there because I've been saying the same things here for nearly four fucking years (post Capitals Online, Oct 2010):
4) There is no effective counter-measure to supercaps other than other supercaps. While it is possible to destroy a Titan or supercarrier with only sub-cap ships, you need effectively a perfect storm of conditions to do so: a tackled ship, a few hundred of your allies, hope your opponent does have a hundred or so of their sub-cap ships, and enough DPS to kill the ship in 15 minutes if he logs off. On the other hand, a small handful of supercaps can hotdrop a tackled titan and kill it in a few minutes.The stagnation in null sec is killing the game CCP, and its really starting to show. You're running out of time.
But beyond that, a fleet of enemy supercaps can't be stopped by anything outside of a fleet of your own supercaps. Or a hell of a lot of regular capitals or metric shitton of well coordinated sub-caps, neither option which is very feasible for your average every day operation. Thus "supercap blobs" are well nigh un-counterable, and POS defenses are inadequate to deter these fleets.
Fundamentally, you need supercaps to deal with enemy supercaps.
