Dude that sounds so needy… you get a 3/5 - 4/5 roll for free but “oh no everyone else has one too.” Bungie is giving you a free curated roll, if you aren’t content with it, that sounds like a you problem.

You can, but the appeal is getting the good rolls so you don't have to have multiple weapons in the vault. I'd rather have one good weapon with double perks, than 4 of the same weapons with single perks. If Bungle really wanted us to have more vault space, the easiest solution is to have multiperk rolls drop reasonably enough for as much as possible, so they don't have to expand as often, we still have to grind, and we don't have to carry as much on us if we're engaging in PvP and PvE. Get a good perk combination and you're covered for multiple activities. It is definitely difficult to get the right double or triple perk drop. Takes alot of time and engagement. I've done that alot with Vanguard and Crucible stuff. I'm ok with that though, it feels more worth it.
