Drop Shotting Nubs

After a long day at my wonderful school I started to play some good ol' COD. After a long wait to get into a lobby in World At War I finally got into a hardcore match. For almost an hour the only way I would die is by the same guy with a Thompson drop shotting me. This guy could do nothing else but drop shot and everyone else in the lobby was having the same problems that I was. So people who might read this, what do you think about drop shotting nubs?
