How can Bungie fix this: Disturbing thing in rumble - people are clearly joining up together in a fireteam and trading kills. Probably to finish those quests super quick. Like the 15 sniper headshot kills and maybe even for the legendary weapon thing. When you see two people have very similar scores above everyone else and they only seem to kill each other.... Since you get +50 for killing whoever is in first you can trade that off and boost up.
