You are truly showing your ignorance now.. "Truly randomized" does not mean you get something different each time. You ABSOLUTELY would expect duplicates in a random system. Now, I agree some items might be weighted. That's still random, though. However, your notion that the game purposefully locks you out of the gun you are wanting is absurd. You have just as much of a chance of getting an Ice Breaker out of the Gorgon chest as you had the last time you looted the Gorgon chest. I've already had my statistics course in college - years ago. Have you, kid? Because it doesn't sound like it.
