There are flaws in your argument, however. 1: Both Dark Below and House of Wolves are advertised and listed as Expansion I and Expansion II. As such, they are both considered "mandatory" as they lock off players from actual game content. DLC is optional by virtue of its definition, content intended to enhance or add onto what is already present. But never considered mandatory. Of course, the distinction between what is DLC and what is an Expansion is just beating around the bush and ultimately holds no real value to the subject at hand. New weapons/armor were added, shop vendors had their inventories replaced and old content was replaced with new. That is the focus of conversation here, please do not go off topic with me. 2: Unless you work at Bungie, there is no way for you to be certain one way or another that the old gear was never intended to stick around forever. That is nothing more than speculation on your part, and there are just as many others out there which argue the opposite. 3: I don't agree with your logic based on pure common sense, nothing else. Given the situation, presented to a group of intellectuals diagnosing the scenario, it is easily determined that one option results in there being a split between differing opinions while the other option breeds cohesion of ideals. Hence, the two options I explained already. Logic will always dictate what is right or wrong. 4: There is nothing simple about it, on the contrary. If the new gear has different perks then that makes even less sense for them to retire the old stuff. That is the idea, after all, to populate the game with weapons and armor that seek to diversify the gaming experience. If you could elaborate upon why you feel the old content doesn't fit in line with the new, I'd love to hear it. Personally, I'm willing to wager you have the makings of a personal opinion regarding this matter but you haven't fully explored your thoughts on it. My advice? You would benefit from a change in perspective. Its simple enough to do, all you need is to erase your current opinions, step back and then assume the role of an outsider looking inward. Question each thing, and find the answers. Then questions what you discover, and once you reach the end of the rabbit hole you will arrive on the other side far more enlightened and well off for it. Its a technique I find quite useful.
