Destiny should have an option for all exploration parts on Destiny to have a 10x difficulty to all enemies and the loot would be much worth while. You should have only one life and you would be returned to orbit once you die. There could also be abnormal events that could involve many enemies pursuing you with a lot of aggression. This would keep players on their toes more and encourage to possibly take a stealthy approach when it comes to patrol enemies. Since there already are established places where there is a high concentration of enemies such as the sand palace or that big hive cave in Earth, there could be really good loot in those areas as it would be a challenge to go there. As people would exploit this, Bungie would do weekly resets like raids and night falls. Exotic bounties can also be tied in with Hardcore exploration. I think this idea would make the exploration part of destiny much more interesting and worth while to play. it would also make random encounters more appreciated because help would be needed in hardcore exploration
