yup i took about a 2 week break, came back, lost 800 points and haven't been able to get em back since. no worries...it gets to the point where you literally have to get a 10-1 KDR in order to sustain your points (kill a person get 2, die and lose 20)
but i don't really care about the points anymore, just FBG. so right now im working on getting all of my pistol bronze badges, you can imagine what my KDR is gonna drop to for that
