Shadow, work on leveling up to 27 beforehand if you can. The Glass Vault is a bitch. Also work on your elemental selection with your weapons. Just about every single bad guy has a shield that we'll have to take down before we can even get a shot to their noggin. I've got a full legendary set of armor, two legendary guns but I want that exotic before I go and I want to be level 27. Hopefully Xur will have something for sale that I can afford as I'm not sure I can grind through the bounty that will get me one. I'm also going to focus on getting to Vanguard Level 3. Screw the Queen and the Crucible until I've got that done.
