Raiding
There is a ton of things todo within destiny. Way too much to even begin listing them. However one activity rises above the rest in terms of players needed, difficulty and coordination. Raids are a staple within and a big achievements for some players in Destiny 2. Raids are a 6 man activity with no matchmaking meaning you have to have 6 players you know to join in and help you. Stated from the destiny wiki themselves "Raids typically involve epic, climactic encounters against various bosses, culminating in intense final battles against legendary bosses across the Destiny series." Like I previously noted raids do not tell you how todo any of it. You basically either watch a video on how todo it or somebody that already knows what todo teaches you. On top of that raiding on average takes about an hour IF all 6 knows what they're doing.
