Search the forum for Lag Compensation. You will find that the majority of people, myself included, who end up as host get screwed by lag. If you have the best connection in the lobby you will get host, so your friend having less bandwidth probably contributes to the situation. In an effort to level the playing field and eliminate host advantage, something went wrong and instead puts an extreme disadvantage to the host.
The game is nearly unplayable for me as host. Forget run and gun.. even camping dosent help. Its like bringing a pillow to a gun fight. Absolutely hopeless at times, especially against spawn trapping DB clans. I have quite more games in MW3 than all the past COD titles combined.
I am hoping that hotfixes and tweaks will one day solve the problem. It would be nice to have a full night of evenly matched games without the outcome influenced by lag. One can dream right?
