People 18 and under get most of the blame but are not always at fault. No, he's considered to be defending the flag. No, he's considered a camper. Whereas, in TFC, you can take a shit-load of damage, die, then run back to the same place again, in CS, you take two shots, die, wait 5 minutes, and then the round starts over again. This death sequence is meant to reflect how in real SWAT missions, officers do not just pop out of the ground again.
Camping is a strategy used in the real fucking world, and few people seem to realize that.
The more it promotes camping. No, it promotes camping. Any map or gameplay style that has objectives of any kind requires a defense, and defense by definition means attempting to overpower any attackers. There is no other recourse. I therefore refer back to my original assumption that most people who play CS are just stupid.
