Wish there was a self-insert customizable male human/other character. Would be nice to guarantee female slaves produce more female slaves if needed. Also, would be cool to have your own room for the self-insert that you could upgrade or would get more grandiose as you conquered stronger raids.
Why produce more slaves if there are already too many of them? There are only 6 or 8 places for conception (I don't remember now). There are also about 8 places in the nursery. And only three tables for childbirth. Further, if more girls are born, then fewer warriors will be born. And preparation for the raid will drag on.
In short. Three goblin girls are enough for me (two for goblins, one for abomination) with a birth counter of 100 each. Not slowly but not quickly either.. Plus three elves (6 in total) for milking. All named (well, except for the cat girl, there was not enough room for her) - in a brothel, they earn money, because it is impossible to raise their birth counter).
On endgame raids. Basically, this is the alchemist's tower, there is nothing to do in the dungeon (if you have already farmed the succubus) All you need is 18 warriors of level 60
And all that remains is to change the elves at the milking and sell the extra hybrids
