I think the simple answer is "randos" (Destiny)

I don't understand where the confusion is coming from; he spelled it out very well.

He often gets matched with folks that sprint through the whole thing, largely skipping encounters, not allowing any exploration because the game forcefully drags you along with the player in the lead. I don't believe that doesn't match your experience when going into strike matchmaking, as it happens in about 90% of the strikes I've ever played. I would say that a large majority of the Destiny population don't approach strikes as "Let's do this fun activity and shoot some aliens" but rather, "Let's do this as fast as possible so I can maybe get an exotic or get some Legendaries to dismantle for coins."
