You go work 40+ hour week for a year and spend the well hard earn money on a new car. You EARN the money to buy the car. You go in a buy a lottery ticket and WON a million bucks. You WON the money, you didn't earn it. See the difference? EDIT: Do you know that box saids "reward" after you finish a strike or in crucible? That means you won this as a reward? You never earn rewards.
