1-Your in a game and quite merrily killing less skilled players and your quite happy.
Less skilled players leave and better players enter and you start to lose. You now quit because you cant handle being owned.
2-You now re-enter matchmaking and get put back into the same game and you quit again (always amuses me)
3-After you have quit again you yet again re-enter matchmaking and get put in a losing game and instead of toughing it out you QUIT again.
4-This is why your W/L is 0.29 and why your 3.7 k/d is totally pointless
While I'm at it if you use rapid fire with the 74 and have semtex instead of a grenade then consider yourself truly awful and an affront to decent gamers everywhere.
