You must be a huge fan of Destiny then to call it a hand cannon. It's called a pistol for most other FPS games. You can say that Destiny ripped off CoD with their supers, since supers are considered as kill streaks. Supers if you don't know, can be obtained by doing absolutely NOTHING. Kills streaks can't, you actually have to put in work to get kill streaks. FYI: 1 hit kills? most kill streaks are 1 hit hills. So again, you can argue that Destiny stole the idea of OHKs from CoD. Like I said, what BO3 has was inspired by Destiny.
