I'd argue that it proves that you have a big tactical advantage in wormhole space, but you're not invincible or safe. Nobody is, anywhere.
Which at the same time is a bit of a shame; I wouldn't mind having my own space station in high security space with no risk of losing it by another corporation. I'm more of a casual base building turtling kind of gamer than the pvp type.
The number of bodies was a very small part of the story. Like real wars this was won almost entirely by logistics.
Though I suppose, in the vast emptiness it might be difficult to find someone else. But a ‘radar’ that helps with it could have a limited range.
The entire topology of wormhole space is constantly shifting with wormholes appearing and disappearing. Hole control is paramount to fighting on jspace.
CCP finally decided this is not how they want the wardec system to work. Now, a corporation can only have war declared on them if they own a structure in space. Most small corporations have no need for, or enough money, to anchor a structure in space. The idea is if you have structures in space, you should also have the means to replace them if they're destroyed or be able defend them in the first place.
