Will it replace reinforcement spawning and ships sleeping/guarding a guard post?
Yes.
Will an AI planet contain only a station, some guard posts and a barrack shipyard/bay? (And the occasional Threat / Special Forces passing by)?
Close, but not quite. Each guard post would also be a shipyard with bays on it. But otherwise, yes.
And so the Strategic Reserve would be a special, indestructible MkV shipyard/bay?
Please don't laugh, but I don't remember what that is at the moment.
If that tech level would be reserved for waves and the reinforcement would depend only on the planet's mark, that would be a neat improvement of the game's readability.
I was not planning on this, but based on notes from Keith yesterday this is the current plan in the document, yes. So great minds and all that.
Last question: what would happen to the conversion guards->threat? Attacking a Guard Post wouldn't awake its guards because... it would have no guards.
The guard post would still have just as many guards (if not more), but they would be in ship bays on that guard post. So it would mechanically work the same. Actually Keith already has this working I think, though not with visuals.
Would it be "every ships slowly released from the shipyard become threat"?
Probably not... not fully, anyway. Some of them would come out, fight off a threat, then go home. Others would become threat, as now.
(And the shipyard would continuously release ships while Humans are on its planet?)
Maybe, but probably not. It probably has more to do with proximity to the shipyard, but I can't decide on that. That's something that would have to be experimented with. The shipyard itself might provide a stream of FRD-style AI units that go back to the shipyard after defeating intruders, if they do. Whereas guard post guards that are released from their guard post because it was destroyed become threat instead.
But there is mention to ships being healed when returning in a bay. I'm confused.
Aggro wouldn't be irrevocable in all cases, basically.
So long as the UI both in the system view and galactic view lets you easily discern the garrison of the ship bays though.
For sure!
