I'll be honest, I haven't quite read this entire thread, but I was responding to the original post. xP
I must say that I enjoy all four classes, but out of them, I enjoyed a LS Agent... and I will NOT hesitate to go through the story again as a male IF they allow SGRAs and Vector is the Agent SGR companion.
I find it incredibly awkward going through as a female anything... (even though, I'm gay and it'd probably work out better for me romance wise.
Until then I'm good romancing a DS Jaesa on my Chiss Warrior <3 She may be a girl, but she's awesome... I'd totally date her if she were real... and I was the Sith Warrior in reality. xP)
