I've done a lot of HM FP duo runs with a tank + healer w/dps comps. After seeing your guide, we decided to duo Black Talon HM, for the weekly HM's mission, using a mostly Rakata geared Powertech and Tionese geared Marauder with Tionese geared Mako and Quinn. Took about a half hour, and we did it smoother than using the tank + healer combo with dps comps.
Nice! Wish I could do BT on republic side. Added your tip to the guide
