As a woman (and a disclaimer: I read primarily fantasy) what I would enjoy seeing more in books is female characters that are strong, yes, but who also fit the world the author has created for them. I'm sick and tired of the princesses who swear off dresses because dresses are so limiting and misogynistic and who run away with the stable boy the moment their daddy the king breathes word of a possible arranged marriage - in a country where all women wear dresses all the time and arranged marriages for the upper class is The Done Thing. I'm not saying the characters have to like dresses, or want an arranged marriage, but if you spend 16 years knowing that your marriage will probably be arranged for you, it's not going to come as the earth-shattering shock that I've seen in So. Many. Books.
There are a lot of overly-stereotypically-feminine, passive, need-to-be-constantly saved types, and there are a lot of incredibly-stereotypically-masculine, aggro, badass types. What I want to see are the women in between, who are strong at some things but need help with others, who are right about some things and wrong about others, who've made mistakes and learned from them, who are mothers, sisters, daughters, great-grandmothers (honestly I just want to see more family and fewer orphans/runaways) heroes, villains, best friends, rivals and more.
I'd like to see the same range for the men, too. But with beards. :P
