Yes I have I have 3 completions on hard and I know how to do it. On hard mode dispersing enemies can bring more harm than good. Also how is DB going to be useful on Ir Yut and Crota? I'd kick you from my fireteam if you said you used DB over Ghorn. And dude you barely have any completions for the raid you have no idea what gun would work in CE hard. Don't try to comment on something you no nothing about.
