•progression has been reworked entirely since the game launched. Leveling from 1 to 40 is now based entirely on your own actions.
•A new behind-the-scenes reward system pays attention to the gear and weapons you already have, and not only attempts to avoid giving the same reward multiple times, but targets you for new loot that will be valuable for progression.
•You can carry more bounties at any one time, and turn them in without returning to the bounty giver.
•the Cryptarch more reliably provides rewards that match the engrams you give him.
•Quests provide meaningful story progression, and clearly trackable paths through all the game's content, thereby lessening the grind.
•The Crucible has improved matchmaking, and a mercy rule ends matches early when any given contest is dramatically misbalanced.
•Crucible heavy and special ammo drops and economies have been reworked to be more understandable and useable.
• Weapons have been balanced across the board, with the aim to eliminate the dominance of just a few weapons, and make every weapon type a compelling choice.
• Whether your gauge is number of Crucible maps, exotic weapons, or playable mission, Destiny now has more than twice as much content as the original release. While Taken King introduces the first fully explorable new gameplay area, the new story mission zones, raids, and arena add substantial real estate to uncover.
