Yea, it is a legit start and no one has the right to tell people how to play the game... If they are scrubs and all they do is Camp, so be it! Who cares if they got no skills, people have no right to tell people how to play games...

Woah..took it a little personally there huh?

Well... its basically like when I knife someone while I am a sniper back in mw2 days and the 12 year old yells like a girl on her period saying "You are a sniper, you can't knife people you bastard." which is annoying as fuck And I am like "Go back to elemantary school you 5 year old whore" and etc... People should be allowed to play games anyway they want because it is their purchase and they spent the money to be able to play like that... I just hate when people try to control things that they shouldn't be allowed to control

There's a problem with your analogy , with a real life LZ  you have the option of being able to clear the LZ before you land .

Camping is one of the possible correct tactics for a real life sniper. But in real life the world is far bigger and it's more difficult to predict where enemies will come from, except through unavoidable narrow passages, and in real life there aren't spawn and respawn points, so it should be up to devs to allow realistic camping but preventing its abuse against spawning and respawning players.

Yes it is legitimate. Especially if a game is encouraging it by gameplay elements or level design.
If the game designers do not want this behavior there are numerous ways to encourage moving or discourage camping. So if there is a game with lots of campers, the game devs meant it that way.

They camped in the US the previous generation with the 360. lol

I've never camped so hard as I have on MW2. Claymore re-ups with Scavenger perk made it possible to have two out at once covering two entry points while I'd be picking dudes off out of windows and shit. If they destroy the Claymore, guess what, I'd know they were coming. If the Claymore kills them, scoop up another and replant. It was so unfair combined with a 5.1 headset.  Black Ops was the Camera Spike.

Anyway I love to camp on MW games but never on Halo. The hate mail I receive is precious, that's when I know I'm doing it right :)

I don't camp in every game, but camping in COD is the best strategy. Some people get butt hurt and say it's noobish. But what works, works.

I remember it being a problem in World of Warcraft too. Sometimes it just someone being clever. Other times it an unlovable person finding the only way to get noticed in the world by ruining other people's good times. Those people suck.
