First off, I realize that not everyone is a collector, but for those of us who are, Bungie seemingly willingly complicates our efforts. There wasn't enough vault space in vanilla Destiny, and the new gear in TDB made it an even bigger problem. Bungie's first attempt at a fix was to increase vault space from 20 slots for each category to 36 weapon slots and 24 slots for armor and general. This initial vault expansion was made in anticipation of HoW in an update that came out in April (according to the 3/26/15 weekly update), but the mistake Bungie made was that they didn't account for all of the new gear that would come along with it. Fast forward to August 20th. HoW had been out for three months, giving us ample time to acquire a lot (in some cases, all) of the gear it had to offer. There was enough noise coming from the community about vault space to be included on the community wish list (https://www.bungie.net/en/Forum/Post/140885111/0/0). In the weekly update released that day, DeeJ addressed vault space by stating "How about if we double it?" (https://www.bungie.net/en/News/News?aid=13414). Once again, Bungie made the mistake of addressing the vault space problem before releasing new content. Along with TTK came brand new vanguard and crucible gear, faction gear, exotics, raid gear, Iron Banner gear, ghost shells, strike specific gear, and quest gear. It also introduced new materials and a consumable (spark of light) that a lot of year one players, like myself, will never use, but can't be deleted. As if this wasn't enough, Festival of the Lost introduced masks (which are awesome) and a bunch of new consumables as well as bringing back year 1 Halloween favorites. As my status suggests, I'm pretty much out of vault space (my armor and consumable sections are full). I know I'm not the only one who wants more vault space. Hopefully if we make enough noise Bungie will add more. Even one additional page for each category would be great. Tl;dr: There has never been enough vault space, and the two vault expansions that Bungie has implemented so far did not compensate for the huge quantity of gear that would be released in HoW and TTK just weeks later. Festival of the Lost has compounded this problem. I also like the idea of a trophy case, separate from the vault. Edit: What if Bungie added a cosmetics tab to the vault? That way we could store the masks there instead of in the armor tab. The vault could be broken down even further by adding a section for class items and ghosts. Here's a link to my thread discussing that: https://www.bungie.net/en/Forum/Post/168231710/0/0
