Let the exotic weapons (none crafted) & Gears be able to claim from collection with the most recent power level you had so we can save Vault space for Legendary items. Example: by default if you claimed exotic weapon you get 1600 power level but if you have upgraded it to 1810 then you can claim it back from collection as 1810 in that way we can delete almost all of them and claim only when required. If you have more than 1 character with a different class (Hunter, Warlock & Titan), in my case I use all 3 classes I need to keep exotic gears with nice roles of each class that consumes a good potion of Vault space so i would suggest to each character with a different class to provide additional Vault space or provide a option to remember your last Masterworked exotic gear to be remembered in your collection so you can pull when you needed. I think these can be a functional way.
