I have so much fun with infected mode. The fact that when you die you immediately join the other team is genius and makes me wonder why other modes dont try it. You win either way! There are always thousands of people in queue for matches night and day. Good, fun play.
The only problem I have is that I have an excellent internet connection, which, in the infinite wisdom of the developers means I get penalized using their lag compensation program (they must be socialists). There are so many times that I shoot 20 bullets right at an enemy and nothing hits. This makes other modes very frustrating to play, with 2 kills due to ambushes being a good match. It is very obvious when watching the kill-cams and I see an enemy run up to me and kill me while I dont start firing till I have moved past him and am in the process of dying! Even though on my end I started firing as soon as he appeared. Sad, but I used to play on dialup many years ago so I learned to deal with lag like that and found other ways to have fun.
Anyways, as a tip to others with good connections, try dropping out of games as soon as you discover you are host (screen goes black at start of match). In infected mode I even drop out when I am first infected since I cant hit anyone anyway.
I heard that you can even try throttling down your connection so you dont get penalized with the fake lag, which makes sense since in most matches the players at the top at the end are all 2 and 3 bar connections, but I cant imagine messing up my connection just for a game unless it was dedicated just to playing mw3.
Something the devs could do that would easily mitigate this problem is to give a small xp bonus to the hoster...I would put up with fake lag if it meant I got an xp bonus!
The perverted logic of socialism even affecting our games /sigh
