Yeah it's extremely annoying especially when you have your favorite map and you are ready to play it, and out of nowhere BOOM! you get transferred to some noob who lives in the UK giving you a 1 bar connection.
It happens somtimes. Im just glad that it migrates the host so we can finish playing them. MW1 didnt have that feature. If the host drops out your screwed!
after i stay in a room for a while and the host leaves i become the host and i have a sweet connection so when im host im hallways the host until i leave
