Neither FPS nor MMO game types offer "door prizes" in PvP, because it doesn't make sense. If Bungie wants to reward the shittiest players with exotic gear (idk why I haven't received my exotic yet), then there should at least be strange coin/mote of light rewards for the best players. So the good players at least get to buy items/engrams from Xur. As it stands, a player who exclusively plays crucible (and plays it well) may never see an exotic item, and that doesn't seem right.
