Item dupes are not the same. Item dupes serve to make the items being duped cheap. In other words, rare items that used to only be enjoyed by the few can now be enjoyed by everyone. This is hardly terrible. In some cases it makes almost no difference (shroud ingredients are common, but you still need 20 runs per item to get rid of the debuff so there is little impact on how much people need to run shroud). Certain augments are now common, but that just means more people can enjoy the benefit of that augment. There is still plenty of loot to collect for people that enjoy that sort of thing, but bugs like this are just part of the inherent flaw of having a game based around loot. This happens in MMO's all the time because we still have not turned the focus of MMO's away from the collection of items (that can and do get duped in games all the time).
