Most queer women enjoy being with someone who is an equal. Also sharing emotions or showing weakness is how women connect with each other. This is why Leliana's romance worked so well. She was a physically strong Rogue character, but had some serious emotional issues to deal with and she shared those stories with the Warden and it brought them closer together. (I also used a mod for Leliana which changed her face to look more "Sacred Ashes" like, and that added *much* to the romance)
I would love to see a romance with my enemy. Perhaps we capture someone and after an amount of time the NPC and me realize there is more a grey line between "friend and foe" than we thought. Love/hate is always fun.
Or I'd like to see someone who is not in my party, i.e., a merchant, a healer, a guard captain, etc. Someone with whom I can still spend plenty of time with/our paths are seemingly always cross.
If they were in my party then someone who, like Leliana, takes a *long* time to romance.
These games are all about being the hero, to the world and to your women.
