I just thought I'd post my little additional advice: Upgrade everything you can afford to upgrade. (I'm level 27, btw.) I prefer to use my T7 for missions, at least so far, so I had neglected Kira's gear horribly. So, after trying everything in this thread and getting very close to beating him, I went back to the Fleet to see what I could find. After upgrading most of Kira's gear through the Galactic market and some unused commendations, and somewhat upgrading my own as well, I went back and beat him easily -- still using the strats listed in this thread though. By comparison, before doing this, Kira died within a very few seconds. When I beat him, though, she almost survived the fight. Huge difference. Good luck!
