Well, yeah, homunculi are not meant to be
too powerful. I'm usually worried that they're still too good, after seeing posts/saves of parties with a lot of them.
Also note that they're quite a bit more useful on higher difficulties, where getting good minions is a much harder process. I think the first three or so are actually better than
anything else you can get on Impossible.
They're
combat creatures, not breeders.
Would break the "good minions come from virgins" theme.
They used to inherit certain properties from their visual template, and that made them
entirely too good. They
can swim and dig, though, unlike Drakes. And have somewhat different resistances.
I'm actually planning to move away from 'girl minions' in combat teams. Females aren't supposed to be your heavy hitters. There will actually be a 'shame' category for using female minions.
I'm not opposed to doing
something with the homunculi, but none of these proposals really fits. Hmm, how about giving them immortality, i.e. they can be 'repaired' at the Coven for some gold when they die in battle? Would take quite some work to implement, though.
