I'm super stoked for this expansion. However, as with any new expansion, the good folks at Bungie have an opportunity to make sweeping changes to the existing game under the DLC banner. For me, I'm very excited to see the Reef zone as well as potential new zones. I also think this is a key opportunity to better explain the Queen. She was far too mysterious in the core game and she needs some serious character development. What is on YOUR list?
