Of my previous brainstorming session, I do like the idea of a gravity command station, after we get enough feedback on the current state of gravity. To flesh it out a bit more:
A gravity command station would be unlocked similar to a warp jammer command. It would affect the entire system, human and AI like a gravity drill, but it would have resource cost instead of income. An odd fit for a whipping boy, it would be a horrible choice for an actual chokepoint as it would very effectively isolate your fleet from your empire. As a target, it would add 1-2 minutes to the transit time through a system, with the point being solely to buy reaction time. I could imagine putting these up around my flanks before a CPA, or in the presence of hybrid hives.
Opinions?
