Right, but now you're talking about the [i]probability[/i] of getting a certain item-in that case you have sequence S={R,R,R,R,R,R,R,R,B,B,B,B}, with Random(S) there's an equally probable chance to select any single item from the sequence. In this case the probability to get Red is twice that of blue. But that's different, that's the probability, or in this case the drop rate, which is usually assumed to be given...that's what I'm basing my tin foil hat theory on, that the probability is not the same for each exotic, thus when Bungie says "it's randomized", they're not lying, just withholding how it works.
