The Blades of Crota are no longer available unless you buy the "Dark Below" expansion pack. Eris Morn is still giving out the bounty if you dont have the expansion pack but you cant do it without the expansion... hmmm... I have also noticed that the "Pack of Wolves" keeps showing up in the middle of areas on earth that i am trying to run normal missions but without the "House of Wolves" expansion pack, I have no hope of defeating them even though i am level 26. So Bungie is forcing us to buy these expansions of possibly not be able to finish normal missions from the original game disc that we paid $50 for. Guess i should just shut up, pay the $20 for Dark Below and another $20 for house of wolves and then whatever the cost is going to be for the taken king because im sure they are going to do the same thing there as well. Wow... a $50 game just became a $100+ game and i still only have 1 disc. Lmao... greedy much?
