Think about this, with Xûr in the game you have 2 ways of getting exotics. Either earn some coin from the Weekly Heroic and buy them or run the hamster wheel and rinse and repeat until the RNG wheel of fortune spins in your favour. The problem here my friend, is that some players have fallen into the trap that is RNG. They have become addicted to the hamster wheel and feel any "reward" dished out by lady luck was "justly deserved and rightly earned" when the fact is they weren't. These rare and exotic guns you speak of were just handed out as the result of a spin of the wheel, a roll of a dice. RNG doesn't care about skill or what you do, it just makes a roll at set points in the game. RNG doesn't care if you ran the VoG 100 times or just once when it hands you a Ghorn. It doesn't care if you have a 3+ KD or a 0.17 when it hands you an exotic at the end of the Crucible. That is why any exotic acquired via RNG is never earned, as they are simply handed out on the bases of luck. Some players need to stop deluding themselves and see the game for what it really is. The way players keep running the VoG each week in the hope of getting an exotic "reward" is the same as the guy who keeps shoving money into a slot machine each week to get a "jackpot". It's like an addiction and it's just a cheap and clever device used by games companies to keep you playing. Players who buy stuff from Xûr generally understand this and on the whole are not suckered in by the other mechanics of the game.
