Ok. Yes I hate campers rather vigorously, and routinely make it a mission to do nothing but chase them down if I get caught by one. So 3 kills would almost surely result in at least one death (ha) but it also means they wouldn't score any captures etc. either. Also, while they might (let's say for arguments sake they get 3.0) get the proposed K/D bonus as it were... that would be ALL they get where everyone else running their butts off would have kills, captures, assists, etc. A clever camper could be a small weakness in the suggestion but I would suggest they are in the vast minority, they attract so much aggro they get vengence killed anyway and the K/D is only one small part.
