Black Ops server

By far, Call of Duty produces the best series of back to back video games; in my opinion. Furthermore, Call of Duty black Ops is the latest version which is my favourite because it has extras such as Zombies, Combat training and wager match; as well as the online battle field. However is said to be that is the most played video game worldwide. In addition, the down fall to this is the Call of Duty black Ops zombie servers and hosts are able to end the game. Several time I have been over level 40 on the Call of Duty black Ops zombies and the server timeout or hosts end the game; I think they should make the scores saves to the leader board when these things happens; or even make host/ player not allow to leave game after certain levels. IS THERE ANYONE ELSE EXPERIENCING THIS?
