I just got done with a raid team when we got to Riven in the Last Wish and I wanted to go back to the start to do the wishes, but there is no way to reset my checkpoint so I'm stuck at Riven. I would love to have it possible for me to reset my Raid Checkpoint so I'm not stuck at one area like we could in Destiny 1. IMO we need a way to reset our Raid Checkpoint in Destiny 2.
