Hmm, AIP-costing I know, and won't work on the mkV parts, but the mkIV groups could be "delayed" (and chewed up if you can spare any firepower for it) via an EMP on the planet they're hitting cyborg from. A desperate maneuver, though.
Ow. It really needs to ratio when it does that.
Ratio to planet count, or what do you mean? I'm open to suggestions
In general I think you're right about the AI not liking an overly tidy player. The planet count is really working against you here too, on 80 you'd have double-or-more the ocean of in-the-hills IIs and IIIs.
