I think one of the things Destiny could really benefit from is more reasons to explore the world. Golden chests are great when you are playing through the story for the first time but they are fairly useless late game. I think it would be great to have chests that only spawn throughout the world once you reach level 20. They could even spawn randomly each week along with the reset and maybe be protected by high level enemies! This would give players a reason to explore beyond simply farming materials and would add much more incentive to play patrol!
