Well... While it's right they're not that useful... sometimes (and I say
sometimes), I find them useful. When you go along the Neinzul path aggressively (unlocking high mark of them and unlocking the
true neinzul enclave mobile spacedock, you may want to use your little short-lived friends not only as a storming death legion but also as a vigilant quick response team. So, instead of being yourself vigilant and building them when you need them, you may send them to the planet you want to defend and add (if not already done) a NRChamber to it : the younglings will automatically enter and exit the chamber and stay (mostly) healthy. When the AI will warp/wave this planet, they will respond as a normal defense fleet.
Yeah, I know, not that useful. But stay, I've got something more.
When you're steamrolling a bordering AI planet (threat-hunting?), maybe you don't want these little guys to eat all your metal. So you build a NRChamber in one of your planets near the battle front, and they will automatically retreat when low life (because of self-attrition or firefight) and go right to the NRC, using no metal at all.
Yeah, NRC are lame. But maybe the game would be missing something if they weren't there. They're a little tool, useful in very uncommon circumstances. Even when I go Neinzul (against a youngster AI, stealing its design backups?) I often prefer my younglings to die in the battle; they don't eat that much of metal. Anyway, 9 mobile space docks kitting with V-click in an AI planet with some MkI-IV younglings in loop are just a death storm (even in homeworld assault).
While I'm thinking...
Maybe we should call this building the
Neinzul Reproduction Chamber.
Just for fun
