Down the Pipe podcast episode 11 they get to talking about wormhole politics and how there seems to be a growing trend of (a) corps uniting together to fight enemies and (b) larger groups kicking out smaller groups in the C5 and C6 wormholes, even if those smaller groups are PvP oriented.
At one point someone said (and forgive me, I didn't write down who as I listen to podcasts in my car) "its like an arms race" in reference to how if a group calls upon allies (i.e. batphones for help) in one fight, then the other side will think they need more pilots (or wants more pilots) because they know a bigger fight is in the offing. Thus the impetus for the the creation of larger alliances and coalitions.
Let's be clear: it is an arms race.
The arms in question are not ships or guns or technological improvements, it is simply a measure of fighting pilots. This is exactly what has happened to null sec, which I've written about before.
I think part of the problem facing wormholers is that the population of that space at the high end sites has become saturated. There are no more free C5s and C6s to move into and setup shop, you basically have to evict someone. And because some of those corporations and alliances in that space have been building up assets and defenses (including capitals) you are forced to go in hard and that means needing to be part of a larger, usually already established group to assist in the eviction... sounds terribly familiar does it not?
What's the answer? I don't know for sure. I have not lived in wormholes enough to even begin to propose solutions, but I suspect that a deathstrike class of ship to negate the powers of massed capitals is a good starting point.
Another idea I had was that perhaps its time to look at wormholes themselves and make them less predictable and manipulatable. They were supposed to be mysterious and hazardous to use... hell people weren't supposed to live in wormholes full time for that matter! It could be time to upset that apple cart and put more emphasis on the hazard of the space and less on the politics of neighbours.
