that's not my experience and that runs counter to the fact that players who are running high streaks build the fastest lb's and as a result are able to pressure teams the most by far because their roles change.

it's all about impact. i'm sure there are players who are completely focused on kills without regard for anything else, but even if they're not doing all the little things that help winning, the way this mode is designed, you'll have an impact no matter what and an even greater one if you're getting lots of kills.
