Camping is NOT cheating. Simple. If someone chooses not to "camp" that is their choice. Nothing is more annoying than people who think the ONLY way to play the game is THEIR way.
Sometimes I "camp" while most of the time I keep moving looking for an enemy. It depends on the situation, and game mode. I use my brain. I like to stop somewhere safe to reload and while I crouch down to reload an enemy may walk past, I am going to shoot him right?? Is that cheating because I was sitting in a corner while he walked in the room???
How can every player be watched to see if they "camp" a little too often and need a ban? Where is the line? Seriously what a awful stupid idea that would be. Banning people because they did not want to run around and be sniped to death out in the open?
Some of the people that complain about this game, it's like listening to little kids arguing at school.
Someone is "camping" wahhh"... well throw a nade in the window, flank them.. or ignore them and go get kills while he waits there alone all round and looses? Or, god forbid, try "camping" yourself if you think it is the tactic to end all tactics which turns you into an elite player. You will soon find out that simply staying in one spot all the time is not going to help you win or get better if you play against decent players with half a brain.
But sometimes it is a good idea to just slow down and not mindlessly run about and die if you are against a team which are good.
