To make things more Challenging for the Daily Heroics, I think there should be an added 310 Power Story Mission (Probably a Warmind Mission alongside a Curse of Osiris Mission). Also, the Challenge should be treated like a knockout list, like say you do one of the 2 280 Power Story Missions, once you do 1 of them, you can no longer do them, same goes with 310 Power and 500 Power Missions. Just an Idea to spice up the Variety of the Playlist.
