Ok, I really need to find the best way to get things organized for raids and other non-matchmaking stuff. Thanks to the Rare engram nerf I'm definitely up against a brick wall when it comes to LL progression, and even if it's squeezing water from a stone when I'm about to get a water balloon that will burst I'd still like to see that content and perhaps get at least one Year 2 Triumph reward.
Depending on what times you play, posting here will be the best and fastest way for you to organize a fireteam. If you want to set up for a raid ot anything, just post a time (and your tag and system!) And a lot of people come running.
If not that, you can also use Reddit (/r/fireteams or even /r/destinysherpa if you'd like someone to explicitly teach or help) or what I prefer, which is The 100 (the100.io) and requires registration but will give you email notifications.
Last resort is destinylfg.net. It's good in a pinch or for those "I want to find a crew right at this very moment" but I've found I tend to run into more shitty people there when trying to do raids, especially if you're new or inexperienced with content.
And I've never used it myself, but recently I learned the official Destiny app actually has lfg functions built off of their forums. Thar be dragons, though.
Edit: I saw you posted earlier about Crota's End: it's going to be a little tougher to find a crew to run that on short notice nowadays since the gear it drops isn't really useful endgame (they haven't updated the loot tables since it launched), but also people here use a particular format for posting raid signups that goes something like:
Looking to start Crota's End at 11 PM EST tonight in hard mode. Never done it but hoping for a fun run!
1) your tag
2)
3)
4)
5)
6)
Sometimes the thread goes so fast posts get lost in the shuffle unless they look like the list above. Don't worry or feel bad; I'm also a little worried once the new raid comes out I'll have a tougher time finding crews for King's Fall. When RoI drops everyone will be scrambling to learn the newest raid so it'll be a challenge.
Don't know what system you're on but if it's XB1 I can help out whenever I can (GT is Holden Cawffle)!
