I have said this in other posts, but we already have a model or method to enable faster deployment of higher tech land:
Support Factories. They just take so long to build, and even more to maintain a consistent rate of production given how BP with EngiMod has worked out.
Why not make Support Factories take less time to build/reduce mass cost and maybe reduce their BP. (If we reduce there cost cost and BP by 33% you keep the same mass to BP relationship. But previously where you could only maintain 2 Factories you can now maintain 3 Factories. 2 Factories will finish 4 units admittedly in the time it takes 3 factories to finish).
This additionally could add reclaim that decreases as you tech, from 80% to 60% to 40% if the controller/owner/army NotCivilian which wouldn’t as such mess with any reclaim on a map.
