Yeah, because that's [i]clearly[/i] all they've been doing.

No, that's not all they've been doing. But you cannot deny that they haven't exactly been working on the problems that really haunting the game. They are more interesting in nerfing weapons and ruining exotics than actually fixing glitches and flaws in the game.

That's because majority of the team are currently working on Destiny 2, and most of them feel like they're done with this game. Yeah they say they'll still support this game, but that only means fixing major glitches and weapon balancing . Both of the DLCs was made in advance before the launch of Destiny so they could focus on the sequel right away. There isn't much to it, Bungie's goal is to make money with minimal effort.
