Once again, I'll refrain myself to jump on mantis and post my "new totally awesome idea", but first submit it to the community.
So sabotage hacking can destroy AIP inducing structures without raising AIP, but not warpgates.
Why not including warpgates in eligible targets for sabotage? (If Chris and Keith didn't, it's for a reason; I really ask a question.) It could provide an alternate gateraid way. It's because saving 5 AIP per planet is too much? But sabotage cost more and more HaP, and HaP is gained by AIP increases... Sounds balance to me, but then why not making a separate "warp hacker" that is maybe more expansive or don't prevent AIP.
Oh, imagine an alternate way of the gateraids that could be both fun and new.
The Warp Perturbator hacker's device can be deployed on a human controlled planet. It creates a phase modulation in the warp grid of the AI that increases in strength with time until it reaches the point where all warpgates on adjacent planets are destroyed. The AI will notice the obvious perturbation and send all it can against the hacker through the soon-to-be-destroyed gates. As this hack can be executed from a defended human planet, the response shall be consequent. Maybe each concerned warpgate would send a full response, so the raw strength of the response is multiplied by the quantity of warpgates. (Note that hacks that are not deepstrikes-like can benefit from neutering and beachheading.)
As gateraids are often done for all gates adjacent to a particular human world, this hack would be a all-in-one bundle. But often gateraids are not difficult, just micro. So as the macro way must be balanced, we can tweak the cost of this hack. Maybe make it has a big-big HaP cost (multiplied by the number of targeted gates) and prevent AIP (it's not free, it just costs HaP instead of AIP, like the regular sabotages, the fabhack or the covert-K-extractor). Or the HaP could be dead cheap but cost AIP like a regular gateraid set, just macro instead of micro.
(I personally prefer the first high-HaP/no-AIP solution, 'cause it's very different from regular gateraid.)
So, what da ya think of it?
