I've been lucky enough to not be plagued by the issues 99% of the community seems to be having - my quests are all fine (yes even Means to an End and my sprint is fine too...). The only issue I'm seeing at the moment (Xbox) is it's taking a very long time (sometimes several minutes) to load into strikes after flying down to the planet, and when you finally do load in, it gives the impression that my fire team is on dial-up connections because they just slowly trickle in (I'm standing on the planet waiting for several more minutes)... and you cannot proceed in the strike until all members are in-game. Should a member leave or any reason, the strike is put "on-hold" until that spot is filled, but you're having to wait several (more) minutes for this to happen, again. Other than this, doing great Bungie!
