I found a problem with host migration in zombies public match.
Black ops 2, Playstation 3
My speedtest.net: 33.80 Mbps download, 4.93 Mbps upload, 9 ms (milliseconds) ping
Host migration happens when a split screen players lag and have red ping bar, in a 4 player game. When host migration happens, I get dropped to main menu, seeing my friend still in game after host migration??? In this video, host migration at 1:24, then near the end of video, the same gameplay in theater mode looking at ping bars. (note, also shows a theater mode problem, microphone speaker on wrong player whenever I talk?)

My router have a feature that can add more ping. I used 300 ms ping for this test. What I did is go do a split screen zombies on my 300 ms ping internet. The results is, it always host migrate and kicks a player on 4 player game when I am a red ping bar as a split screen.

This problem need fixing, don't host migrate and don't kick a player when a split screen player's ping bars goes to red.
While testing with high pings, I can still play zombies mostly fine when I have a red ping bar using a constant 300 ms ping, I find that multiplayer need lower ping then zombies to be playable. Zombies Turned game mode also need low ping due to fast action game play.
