I recently found out that Bungie made an inexplicable nerf to Wings of Sacred Dawn at some point since Edge of Fate, despite the exotic already struggling to find popularity. For some unfathomable reason, they removed its ability to reload your equipped weapon when you get a kill with it, which used to allow you to continue using the exotic's perk (which requires you to aim down sights) as long as you could keep getting kills. I haven't the faintest idea why they felt the need to make this already weak exotic completely useless, but I really can't think of any good reason not to revert the nerf. It was never an op exotic, it was just fun, and Bungie ruined that for no reason.
