I think it's quite stupid how auto addicts hate campers/"stealth" people. Gay as it sounds, it's a legitimate strategy, there's nothing wrong with with waiting in a bush for someone to show up. It frustrates the enemy at the expense of potential kills. There's nothing wring with camping in a tunnel to make sure your flag-bearing teammate has a safe route home. If camping was that bad, everyone would do it and Soldat wouldn't be fun. If campers are "gay" because they use cover effectively and make their shots count, then rushers are too because they need 30 bullets to kill something. If you don't like snipers use counter-sniper tactics.
But yeah, stealth is fun until you get seen - hence - don't overuse it.
And about the scope sound ^^^^^ That's very true, there's nothing like watching a Spaz run by you as you reload, only to see him turn around and "check" the bushes because of your noisy scope.
