I value W/L more than KDR and even then I'm not too bothered as long as I'm having fun.
The K/D ratio is such a bad inclusion that has had such a negative impact on the community with people's attitudes and the way they play. Why not just show kills and mask deaths for public view?
God I miss the classic days of UT and Q3A - nobody gave a toss as long as we're all having a good time, playing fairly and playing the objective. If you won; it was great but if you lost; there was always the next game.
