There should be automatic fireteam formation for raids. Some people don't play with friends online, so they never get to experience raids or get anywhere close to the best gear. Bungie should absolutely add a game-finding process for raiding and level 42 events, like Nightfalls.
Alright, lets see how this would work
>Enters Raid matchmaking
>Wastes 2 hours while matchmaking :searches" for players
<Finds team
>team enters voice chat
>sees team is full of squeakers talking about Minecraft and what vines they watched (yes I'm stereotyping squealers)
>Team is not even 385
>Leaves and gets hate mail from 5 squeakers calling me a poopyhead and a fartface (yes I'm doing it again)
See? This is what would happen
