I was interested in the Leia comics. I always liked Leia. "She's a Skywalker too!" and all that.
Not that I think she has to be a Force prodigy like her bro or her Legends children but she was too often sidelined in the old EU books I read. Make her a good, effective leader. Luke can kick ass during war, Leia can keep the peace and make the galaxy a good place all the other times.
If only she had been Chief of State during the Vong War...
