Which makes me wonder... 2 blood slaves in the inventory of the Primordia Regina per turn may be reasonable, as if having retainers to raise and breed a human slave, not to mention queens do not need them to be virgins... Just protein rich (FAT)
Or immobile Queens could get one automatic blood slave per turn as well at the cost of 10 dying people(think of nephilim script of killing pop), I'm sure insectoids would be real great to play, simulating the tyranids.
