Oh well, can't do Dark Below's Blades of Crota patrols either. New patrol events are coming. Those glowing Taken balls that summon Taken will be replacing them. While it is slightly annoying that some things we enjoy are removed, the point is that each expansion brings the game world into the next stage of the story. In The Dark Below you kill Crota, so having the Blades of Crota patrolling, trying to summon him doesn't make sense once the world has moved to the next story. Same with Wolf Packs. By beating Skolas, we've stopped the House of Wolves. If you think Destiny is bad for it, you'd hate Defiance. The world constantly changes with episodes of the partner series, and world events.

I think I know what you're saying but some people still don't, so with the Legendary Edition you get TDB and HoW but with Oryx entering the solar system the wolves will scatter so new people who buy this edition won't ever experience Crotas minions and Wolf Pack
