CCP Fozzie took a hockey stick(1) to a hornet's nest today with the first dev blog on the new sov system coming this summer. I'm not going to comment on all of it as I'm still thinking about it (but so far, overall, I like it) but I do want to address one statement I've seen a few times.
"This is just like Faction Warfare mechanics!" Or "CCP is bringing Faction Warfare to Null Sec!"
I can see the temptation to think that way but let's change the perspective.
CCP wants Distributed Objective Based Warfare for null sec sov mechanics so that fights for control over TCUs, IHubs, and Stations are spread out over multiple systems, thus leveraging constellation geography to make fights unique in different constellations as well as lowering overall load per node by making large fleets on a grid less advantageous.
How do you accomplish those goals without introducing constellation objectives that small groups can take or defend? Thus command nodes.
Since Faction Warfare is also a Distributed Objective Based Warfare system, but with slightly different input requirements and implementation, its no surprise both systems look and feel very similar to a casual inspection. But a careful examination shows significant differences between the two that will lead to very different gameplay.
For example, in FW the only thing you capture is control of a system which locks the hostile militia out of the stations. To tug on the control bar for that system you need to capture complexes IN that system. The complexes have acceleration gates (except for Larges) that restrict certain classes of ships which impacts the fleet doctrines that attackers and defenders utilize (i.e. T1 Frigates have a very specific role). In addition you need many plexes captured to flip a system, over a hundred, and that's if unopposed.
In contrast, in the proposed null system the Command Nodes to capture a structure are spread out over a constellation, far fewer are needed unopposed to succeed so the time to capture is a lot faster, there are various things to fight for control of in a system (TCU, IHub, Station), the command nodes are not locked in complexes so there is no need for T1 frigate doctrines, and the area of space brings its own wrinkles such as bombs and warp bubbles.
In other words, the differences far outweigh the similarities.
