The grind after power level 400 makes no sense. You require players to dial in -40 power delta misery for a single miserly +2 tier 4 drop, and then add ridiculous objectives against hardened enemies that completely undermines the heart of the game, namely, build-crafing. For example, a high number of precision kills, or so many weapon kills that using one's abilities risks tanking the whole encounter. Really, Bungie? Think about it: at -40 power delta, where enemies can one-tap you, a player needs everything in his or her toolkit just to stay alive. Such objectives make the game nearly unplayable, not to mention anything but enjoyable. At -40 power, it ought to be enough just to survive the encounter. Also, rewards ought to more appropriately scale with difficulty, and at -40 power delta a player deserves more than a single tier 4 , +2, drop., and an "attaboy." Mastery should feel rewarding, not just grueling and exhausting. There's challenge and then there's stupid. Would you really play this game? I'm not so sure anymore.
