I have a 1.3 KD and 1200 kills in trials which is enough to draw a sample size from. Where as in COD and battlefield my KD is 1.7 and 2.1 in BFH respectively. That's because the skill gaps in those games are vastly larger than in destiny. And if you think that it would be hellish and boring why do you think so many people play CSGO and Rainbow six siege and why so many people are leaving destiny. It's because the game modes in those games work.
