I guess I'm Joe-average...my best streak is 34, with a Walker on Tunis harbor, 16 player size and the commander repeatedly tried to bomb me to the stone age. Good thing I like to be mobile, and all the engineers couldn't shoot for shit (literally, half the team was engineers, we're talking like four guys with pilum and rockets)
My KDR last I checked was approximately 2.02 and rising...lol, and this is just my first account, and when I was still learning the game. Of course, if I vehicle whored more often (80% of the time you'll usually find me on the ground) my KDR would be higher, but I'm a team player: winning means more.
Note to self: the War College Ribbon is Ballocks, a 2:1 Win:Loss ratio is tough for a lot of guys, without switching sides to the winning team like a mofo.
