BattleMonkey said:"cheat" scope has zero effect on close quarters combat, so no idea what you are talking about, the issues with it is it's removal of any long range concealment.
BC2 had awful netcode, you would shoot someone and they would at times fall over dead from your bullet a full 2 seconds later. Hit boxes and responsiveness is much tighter this time around. Jumping behind cover adn dying, yea it happens and sucks, but it also happens at times in pretty much every MP shooter, lag happens. I get it far more in the p2p CoD matches and made worse by the huge hit boxes in that franchise.
Are you kidding me? It's a massive advantage in close quarters. In Metro, you can see people through everything, see when they expose an inch of their body. When running around the bigger maps in the close quarters shrubbery areas you can see their heat signatures, pick them off because nobody else can see shit through all that. So no idea what you're talking about. Fucking scope even has the hold breath feature. You can see people trying to sneak by in bushes as well.
And the long ranged advantages are almost just as bad.
I'd take a player hosted Call of Duty game over the current netcode any day, because right now, it's bad and considering the game is running on dedicated servers, it's just borderline depressing.
