You know, I wonder how much of a 'neinzul' feel you could get by having a candy tech unlock that converts a unit into a Youngling version, something like:
* 90% cost reduction
* massively increased speed
* slight reduction in stats
* self-attritions in 3 mins
Then if you start as Neinzul, all your fleetships have that candy tech unlock applied. Some kind of bonus to mobile space docks might be appropriate also.
I like drone spawners, but this might be easier to implement and balance.
