Hello, I'll try to make this brief and on point, My suggestion here is specific to Vault capacity, and I'm hoping that this would provide a practical and permanent solution to the limited space of 600 slot only. The straight forward solution to the Vault capacity is a working and fully functioning 'Collection' tab, allow me to elaborate: First, the TL;DR: Each random drop you receive for a weapon becomes available under that weapon's tab in 'Collection' for you to grab again at any time, and change the kill tracker to be universal. In the current system, each weapon can roll with different perks/traits on it, and because of that we are more likely to keep different versions of the same weapon in the Vault each with different perks just in case they may be needed later either for PvP or PvE uses, and with being limited to just 600 slot in Vault, this becomes an issue so fast, I my self ended up filling the extra 100 slot we got on top the 500 that were available before, in just one day! And this issue will keep going on as there will always be new weapons added to the game, So, the answer will never be in increasing the Vault space, instead, the answer is in having the collection store those random rolls we receive for us, freeing the Vault space to just the stuff we use, without the fear of losing a good roll that might be needed later because it is safe in the Collection and is ready to grab again at any time. How would that work: Simply every weapon in the game has a slot in the Collection tab, for old sunset weapons with static perks and most Exotics those can be grabbed from the Collection easily with a price, but for random roll weapons those can not be grabbed... The solution here is that under each weapon of those random roll weapons add a new tab, this tab will get populated by each random roll you find of that weapon as a stand alone variance of that weapon that can be grabbed again at any time from Collection just like fixed perks weapons and Exotics. Let's say you find the hand cannon Steady Hand with Truesight/Hitmark | Extended/Ricochet | Moving Target | Snapshot, now when you visit the Collection and look under Steady Hand tab you will find this specific roll available there to grab again from collection at any time since you already found it, and when you find another random roll for Steady Hand it is automatically added to the Collection as well, and so on... And this does not add any new information to the game, or crowd the game/collection in any way since each of these rolls are already inside the game waiting to randomly drop for the player again at any time, what is happening here is that after it drop for the player once, instead of having to keep it in the Vault, it just appear under the collection tab for the player to grab it on command, again instead of having to keep it in the Vault or dismantle it and then have to go look for it in the world if it ever become needed at any point. The other aspect of this to make this a practical and permanent solution is to change the Kill Tracker on weapons to become universal for each weapon. Let's say for Steady Hand, you might have different versions of Steady Hand that you use, the kill tracker on all those Steady Hand versions will become universal, so, you make a kill with any of these versions and that number appear on all your Steady Hand versions where ever they are, in other words, the Kill Tracker now count and show kills made per Steady Hand, regardless. Same goes for Exotics like let's say Witherhoard, you get one universal tracker for Witherhoard wherever it is, the one with the Titan will show and count same kills as the one with your Hunter if you keep two copies of the weapon instead of moving it around, and same goes for random roll Exotics like Dead Man's Tale. And I would like to say that this should reflect on Collection as well, so, since it is one universal tracker, it should be stored with the weapon directly in Collection, and when ever you grab that weapon from Collection it should come with the kills counted on it. This I believe will reduce the need for Vault space to just the armor used for different builds, the currently being used weapons and infuse weapons/armor and maybe some materials. Which will help solving the Vault space issue permanently. And to even make this future proof, to help finding a specific roll for a specific weapon in Collection, a simple filter like the one available in game for Eververse Archive (the Filter Archive) can be used with perks available as a drop down menu to filter the collection by it to find what you need fast instead of having to hover over the icons one by one to check for the perks. That is all what I wanted to share regarding this topic, thanks for your effort and wish you all the best. Best Regards.
