There really should be a way to punish people who speed run their way through strikes and nightfalls. Too many times I watch someone sprint through all the champions to the boss forcing everyone else to come along and get trash tier rewards at the end. Even in the playlist there will be people running passed everything and causing them to despawn, making bounties and overall quest progression near impossible in a timely manner. This should be addressed since Bungie already had to make a patch for the streak bonus since if you got joining allies it would reset your rank.
