Don't forget that some people play crucible trying to complete specific bounties/missions. I'm not that good at crucible normally, but if you add in all those games of me trying to get imprecation/sword/last word/grenade/and melee kills and nothing else, it'll bring down my average. Didn't think this needed to be said, but people should not assume every game you give your all and is indicative of how good you are. Some games you just like to have fun and dick around
