Comment 5 for bug 895031

"There may be an advantage to using a slave logic though; if used as slaves, the individual slaves would, instead of having attack missions decided by the spawn hub, select their own targets, meaning many targets could be engaged at once by one spawning hub defense."

Then presumably return to hanging around outside their spawner or entering it & disappearing Slave Miner-style. Which is something I'd like to make use of at least, although I agree that better spawning logic would be nice to see.
