To any solo players who don’t want to talk to people but still want Last Wish weapons: now is your chance
Do a bit of research on how the Kalli encounter works (plenty of guides out there and it’s extremely simple) and then watch a video or two of how to farm. There’s a couple different methods out there so decide which one you want to do and go for it. There are plenty of lfg groups farming the encounter with no mic, so you don’t need to worry about your social anxiety or whatever your reason is. Runs only take around 3 minutes if you’re doing the challenge (which is also extremely simple) and less if you’re not. It will only be the weekly raid for the rest of today and then whenever it returns, but because it is so easy to farm without any glitches, you don’t need to worry about rushing before they fix anything.
As far as loot goes, unlike most other raids, each encounter has a chance of dropping any weapon, so all you need is this one encounter. Also honestly every piece of loot is at least somewhat desirable, so just farm til you’re content. I strongly urge you to do this if you want any of the weapons.
Edit: I should also mention you get a shit load of seasonal engrams and weapon xp and whatnot
