Checkpoints have been an issue almost since day one in Destiny. Bungie are against anything that gives players control so do not hold your breath. Lack of them does not acknowledge real life where you have to leave for a legitimate purpose and cannot save your progress. Yet another reason for not playing, not prepared to put up with this sort of crap so my time is limited now, it seems the rest of the player base has similar issues and must contribute to the low number of people playing.
