I'd be much happier if servers did away with individual scores entirely. No individual points for a frag, or a cap, or an assist, or a defend. If your team caps, your team gets a point. That's it.
I've had plenty of TFC games where I kicked ass (okay, maybe stonewalled, because I play Engy D), but still wound up with a negative score. That didn't matter... the big goose-egg beside the other teams total score was what counted.
It's the land of the brave, and the home of the free, where the less you know the better off you'll be.
