Cause that takes effort, a concept countless people aren't familiar with. Why use a scout rifle which you have to aim down the sights and pull the trigger a few times when you can use cheap and effortless tricks like Thorn's poison, Vex, Hawkmoon's lucky shots, Red Death's heal as you shoot. Welcome to the generation of hand me downs. Whenever I get killed by something else other than those mentioned, especially scout rifles, I salute them for their effort to earn their kill.
