Now the hope we can nurture is those flrts will be actually flirtatious. I played Vette's romance with my warrior and some of them were like "hu? is that flirting ?" "
I kind of suspect that some of the lines there are the same thing a female SW would say....only difference is that the male version is marked with a [flirt] and switches a romance flag on.
On the flip side, I've seen some flirty dialog unmarked (though this is rare).
