This isn't a defense... They know the situation is fucked up, but they are powerless to do anything about it...
I remember when Halo3:ODST went from being an expansion to a full fledged game, complete with launching at full price... People were pissed, both at Bungie and at MS, but it turned out that there was a ton of value in that package.
Fast forward to today, and it's like Bungie completely flipped the script and sold their soul to the devil... Instead of being pleasantly surprised at how much I got from my destiny purchase, I was shocked at how much I had to spend in order to have a decent experience.
I don't know how much of this is Bungie's doing and how much is Activision, but I do know that the name 'Bungie' is severely tarnished in my eyes...
