There absolutely does need to be some kind of balancing of the dialogue options. There are way too many in which you can only be flirty or mean. Some neutral, charmingly clueless or even downright emotionless responses would be good.
I've noticed that too. Just had a convo with my smuggler and Risha where he downright yelled at her, telling her she's not his type while the other too were flirt options. I found that a little odd. A polite decline would have been sufficient. It just really didn't fit the way I play hin.
