It's helpful to always have a finished sv/cv/base blueprint so that you will never be stranded/dead upon something unfortunate happening. Easy way to save your skin/never lose a run :)
For clerification, you don't have to place blueprints when they are finished. You can just keep pumping out more blueprints and wait until you need them. I always have atleast 1 of each type of useful structure(base/sv/cv/)finished, so that i can place them whenever i need them. I usually have like 5 of my fighters ready at once,actually.
That's pretty cool. Should totally be more deeply integrated in the game - and I'm pretty sure it will be !
