It' also boring. And it isn't a feature of the Gothic genre that Ravenloft is supposed to represent.
It's not at all boring, because the Darklords who want power or control or knowledge are also engaged in activities that the PCs can also engage in. The PCs can try to stop the DL, can try to
help the DL, can try to gain the power/control/knowledge
first, can try to negotiate with the DL about it, and more.
The Darklords who want to ruin other people's relationships because they can't have one themselves are the boring ones, because that's all background stuff. It's not something that can be used as a plot, unless you want to screw over any PCs that are in a relationship.
This is it. You aren't arguing for new female villains (which we all know we are getting), you are arguing for the removal of one you don't approve of.
And by implication you appear to be saying women shouldn't want romance or a family. That these are not valid goals for women.
Wow, did you deliberately misread
everything I've ever written or what?
Give the female villains something
other than
only a desire for a man or baby. If Ivana, Jacqueline, and Gabrielle still desperately want a man, fine. But they can also be
actively engaging in other pursuits at the same time.
Are you
seriously against the idea of these women having something to do with their lives other than pine?
This is getting into Ship of Theseus territory. Ravenloft was created to be the Gothic Horror campaign setting. If you remove the gothic, is it still Ravenloft?
Women with non-domestic goals does not equal non-Gothic horror. Especially since the
romance associated with Gothic Horror doesn't even actually
mean love; it comes from
novel, meaning "book written in a romance (Latin-derived) language." A book for the masses to read (i.e., not a scholarly or religious text), and as a genre, Gothic literature influenced even pulp novels and comics in the 20th century. It's a very broad category of fiction.
Gothic Horror is about the dark, primal emotions, the morbid aesthetics, and the people involved having unwanted destinies and karmic fates. You can get that with a female darklord with a non-romantic background!
And none of that prevents you from running plots that
don't involve the Darklords, which for me at least is something like 99% of all of my RL adventures.
