Hate systems like that! What about if you've got to go have dinner, or are having lag problems.

It's no fair. :-/

If you have to go afk just go and be afk until the match ends. It's not why they implemented the penalty system. It's for people who freqeuntly "hate that map" or "fuck that I'm leaving" and go off leaving the teams unbalanced and turning the match into shit for the other 9 remaining players.
Also nobody turns on his PS3 and wants to play 5 mintues before turning it off again. Just ask yourself if you have the next 15 minutes it takes to play another match. If not, why even start a game. If the mafia breaks into your house and you can't finish the game just turn off the tv and leave the ps3 on... you won't get a penalty.
If ND is reading this right now, here's my ridiculous idea: Implement a "turn off PS3 after the match is finished". It helps people who don't want to spend 1$ more on electrical bills and still prevents ragequitters and people who tend to hate maps to switch to a "better" game, in combination with the cash penalty.

There are a few other flaws though.
The penalty which locks your upgrades for leaving a game (I got a already purchased taunt locked up until lvl50). That's not necessary (40000$ is a good punishment on its own, it takes you at least 2 hours to replay that money, but this shit is just frustrating). I was fined because a friend of mine lost the connection to multiplayer matches 5 times in a row up on connecting and I quit the games cause I didn't want to him to wait 15 minutes until we try again and get the next fail. I don't know a solution to this proplem.
Second: Some games start with unbalanced teams right away (5vs4 players on connecting to a MP game). MW2 does a better job here as it connects a new player instantly. I don't know if this is a exploit that some people are using to avoid maps or if it has something to do with a faulty network.

On a personal note: YOUR GAME IS FUCKING AWESOME!
