So true. When I got COD4 I didn't care what I did, I was like a 0.5 K/D player, and usually dragged my team down. I played W@W for a while, and got more experienced and got better. I felt bad when I lost, and my K/D was averaging 1.00 every game, I got bored eventually and went back to COD4. Then MW2 came out, and I was above average, getting around a 1.3 - 1.6 K/D every game, I was still not too bothered if we lost, cause I didn't care about my W/L... Then Black Ops came out and I was pissed off when my team all went 5-18 and I went 30-5 averaging a 2 K/D every game, I went back to MW2 eventually due to boredom and played S&

, I usually did the best on my team, but we still lost due to crappy team mates.
Now MW3 is out, and if my team loses, I always blame it on Lag Compensation/My Team/Inconsistent Guns/Splitscreen Players because they usually are to blame. I'm out there getting 25+ kills a game, averaging a 2.3 K/D (before I got banned on reset for nothing :FU

, and its in this game that I actually start to rage, I'm fine in COD4, MW2 and Black Ops, but in MW3 I just rage because the game is so crap. I question myself why I'm even playing these games, it's because I expect the next COD to be EPIC and its always WORSE than the previous title... I've started playing BioShock and got that game in Platinum, now I'm starting Uncharted 3. I always feel calmer on these games, and its only now that I've started playing other games, that I realize how bad this series has become.
Now excuse me while I go play some MW3 and chuck a brick at a window /facepalm
