I searched here and couldn't find anything either. I'm on this step and found that Mida kills or kills with full auto scout rifles do not count for the "6+ kills with a scout rifle". I can somewhat understand the full auto scouts but there is no reason the kills with Mida shouldn't count. There is nothing anywhere that I could find officially stating the kills with Mida didn't count. I started thinking that I just wasn't getting the kills with the Mida or one of my full autos but then I actually counted the kills. I also went on Destiny Tracker and checked my kills. I should have completed it by now but I'm only at 1 because that is one I got the kills using Boolean Gemini. My other 3 were with a full auto DIS-47, full auto DIS-43, and my Mida.
