While I agree with this premise, this isn't what they designed. Are people suggesting that Bungie didn't test this model extensively before releasing? That would imply they don't know how to design a balanced game with variety. And this would then lead to constant adjustments, in an attempt to fix this. Surely after the first few tests (before releasing the actual game), this behavior would be modified enough that balance would be restored, right? Either that, or sales are on target, and Bungie doesn't care until next DLC purchase.
