You know what the funny part is? My wife got the vanilla game on the PS4 like, 2 months ago and all the content in it is from House of Wolves. Which means that when TTK does drop, you're going to get the whole level system and weapons from the vendors as well. So people who don't buy it literally are not missing out on a whole lot, just the new area and subclasses and the raid. Big whoop. Its not as if TTK is going to actually fix the underlying problems anyway.
