Haha indeed, i have incredible internet and have the similar experience, every other game is absolutely fine, what can you do? Absolutely nothing except change what you do, learn from it and move on. I will proceed with caution when IW/Sledgehammer releases a game in the future, this experience cost me 120.00 and i learned alot from it.

Many have as well, many have no idea why it plays the way it does which is even more interesting.  Good luck and i hope you enjoy whatever else you decide to do instead of playing MW3, suppose you could spend more time on the forums lol Cheers mate!

QOS wont do anything to lower your ping, set mine to 56kbps up and down still went into rooms with full bars its ping not bandwidth that matters.

Haha. Nah, Mac especially has been around these parts forever, and is a trusted source for networking advice, as you know. Any new problems presented by this matchmaking update will be the fault of the IW devs, as I think the premise of this new matchmaking system makes sense.

The way I look at it, the matchmaking couldnt possibly get any worse( well, I tell myself this every time they update the game, and yet they continually surprise me), so it will most likely get better.

You are asking the wrong person. The lag compensation is very hit and miss on players with good and bad connections alike. Some players with faster connections may lag while their neighbor does not. The number of people who are siverely affected by it is fewer that the ones who are not. And a company is always worried about keeping the majority happy. It is my opinion that they have been working on it for so long so that the do more good then they do harm as some other patches have.

I don't think anyone is looking for an advantage. Right now, the weak connections are causing the strong connections to lag by a second or more. I think he just wants it balanced as do I. No one is looking for an advantage, just a fair game.

I actually agree, its worse now than on release, the last patch was terrible for connections.
