I'd say my biggest issue is with the Lost Sectors Bungie made them seem like they would continue to make it fun while in Patrol. The fact that the Lost Sectors stay at their original level settings makes it just a pain that you're going to get through and you can die as much as you want. They could've made them so much better 1. Raise the difficulty once the character hits level 20 2. Make the rewards more interesting/unique once the character is level 20. For example make an Armour set for Lost Sectors. 3. Make Lost Sectors like the areas in Strikes that if you die you have to respawn from a checkpoint and restart the area(respawn at the start of the Lost Sector) etc.
