Campers are the worst next to those who use clients in my opinion. I don't know how many campers I have encountered out of my 800+ games in duels, but I can say one thing, campers don't win. It's just the matter of playing it out right. Anyways, if the person is going to camp, you can always leave. It's not like you take a death. Sure they get a win, but the amount of kills in your stat is the only thing that shows. And that's if you are in the leader board. In my opinion blocks shouldn't be removed. Although there are people who use it to camp and such, it is part of the game mode. I have had some insane battles with some friends with the eggwars kit where we would place blocks in front of each other and fight. Just my opinion :P
