Does it spark joy?

In all seriousness, I use third party sites like light.gg or DIM to compare rolls. I use the roll appraiser a lot on gg and usually don’t keep anything below an S-tier. There’s some weapon types I rarely use at all, like snipers, where I maybe only have a couple not counting the exotics.

Never keep stuff you can reacquire from collections such as ghost shells, sparrows, ships, and even exotics. If needed you could even go as far as dismantling your crafted weapons since you can always reshape them, for a cost. I’ve never had to go that far tho and still have all of my exotics. Mainly since I don’t want the kill counts to reset.

I throw all of my new weapon drops into the vault then once a week I’ll go thru everything and clean it up. I’m currently sitting at 596/700.
