This is awesome, I pretty much do all of these. Don't forget to check out the comments. A good alternative for hive based bounties is the siege of the warmind, save the checkpoint right before entering the war room. More thrall than the dark beyond. Also, if you're having trouble resetting a mission use the square button when selecting the mission and then do the same when changing difficulties. When you hit launch you'll be prompted to accept the restart. Thanks dru, I shared this in the rocketsauce group as well. Good stuff.
