I must say I'm amazed by the amount of host migrations in this game. Today was the first I've played Black Ops 2 in about two weeks and the very first match went through 5 host migrations because of idiots leaving nonstop on the opposing team. I must say well done on the probation policy. It doesn't seem to be working very well. On a side note I still haven't had any lag issues as others are posting about daily.
