Same. I have so many Go Figures in my Vault, most of them not yet MWed, with all different perk combos, and while I try to take them out for a spin in Crucible when I can, without a firing range or some other convenient way to decide for myself which perk combos best suit my playing style (or even which ones are any good) to know which to keep and which to dismantle, I pretty much stick to my favourite MWed guns on my main, because they're usually the only guns with a hope of fighting the current meta. And that's just Go Figures; I have plenty of other guns of various archetypes with random perks that I've yet to even shoot anything or anyone with, and I'll never get the chance so long as there's no easy way for me to try out guns and their perks, and no quick way to figure out which to keep and which to throw away, let alone upgrade them fully to Masterworks. Why even have a Vault, or have so many guns, if Bungie insist on making it so difficult for players to know which weapons and armor are worth keeping, so that we end up never actually getting to use even a 1/10 of our actual stored gear. We probably wouldn't even need so much Vault space if we just had an easier way of determining which guns and armor we like so that we can hurry up and upgrade said gun instead of having to hoard all this stuff in the Vault and wait for some rainy day to go grind ECs.

Go on patrol and shoot your weapons. Literally takes 3 minutes to test out.
