Imagine this:
You and your fireteam are running it down in a GM nightfall, but then you get a random disconnect and/or crash and restart the game. You log back on and guess what? the nightfall is ruined. Is it really THAT hard to just enable rejoining for the guy who got kicked on the character he started it on?

You’d have trolls booting people and then inviting their friends to collect the loot.
