I can appreciate what you’re saying, but it’s kind of like action adventure films. They mix the genres because the audience they’re targeting wants that. So, if women are interested in romance, they can expand the fantasy readership by putting that in there. I’ve read some that aren’t bad and some that are pretty tiring, but Allen Dean Foster wove a romance element into the Flinx series now and then, and it was a key part of the Spellsinger series. So not really just a women-only thing, and likely for the same reasons - expanding the market for the books.
