Good, stat-whoring is the cancer of the gaming community.
Exactly, All It leads to is hostility.
Personally I am a EXTREMLY competetive person, and even though I generally get high Kdr I don't enjoy being so focused on it, and because of the focus on it, I get generally annoyed when I perform below my average.
as for k/d being the reason some people play, this is not true and never has been.
The only purpose of k/d is bragging rights, and if having the ability to brag is your reasons to play a game, then mabye you should do something more meaningful, like building a school for the poor.
