You've got a really good K/D, no idea why you're asking, as the answer is obvious. On the win% thing, the users telling you you're only good if that is high, don't pay attention. I have a pretty good K/D myself but have lost more than I won. I get thrown into matches that when I enter the game are losing 850/300 and stuff like that (Big Team Slayer this is). Of course I end up losing those games.
