Destiny has a story. Its presentation, however, is something to be desired. I understand if Bungie was aiming to tell the story in an indirect manner similar to the lore in Dark Souls; however, Bungie failed to accomplish this. Players were left with no sense of purpose as to why they are fighting these various alien races other than "they serve the Darkness, and the Darkness is bad." I've looked a bit into the lore of Destiny myself, particularly regarding the Warmind and Atheon, and there is some rather interesting information on both of these constructs (which instilled in me a greater sense of purpose as my fireteam purged the Vault of Atheon). Overall, improving the storytelling in Destiny would significantly enhance the experience in my opinion.
