I have every exotic, raid weapon, and IB weapon beside the pulse (some multiples) and regular legendaries as well and I still have a ton of room in the vault...I don't understand how people have run out. I mean I thought I collected everything (which I do) and I still have a lot of room. Start getting rid of those random legendaries that you don't use...you def won't use them when HoW drops and you can re roll new legendaries.
