One thing that is simply not up for debate is the nature and intent of Bungie's RNG system. Behavioral Game Design 101. Getting drops gives you a shot to the pleasure center of your brain. So yes, RNG is made so that you want to keep playing, pursuing that White Whale, if you will. If this was not the case, then they would have included a game economy and a trading system, like the one in Elder Scrolls Online. Any rare item is available in that game, if you have the currency to pay for it. People who are smart witted learn to make money buying as selling crafted items, and therefore become good at getting their hands on rare gear. Destiny is a slot machine, pure and simple. You either accept the odds, or you play something else.
