Uh, Treyarch developers admitted over and over again that they are huge fans of Destiny. If they were really that ashamed to be "ripping off" Destiny, and didn't want to be found out, wouldn't they at least be smart enough to pretend they aren't huge Destiny fans? People think people don't know how to lie, or aren't clever enough to hide their motivations. I guarantee you, the mere fact that these people program and design games already makes them about 10x smarter and more aware than you, Joe-Schmoe the Keyboard Warrior.
