Brink is incredibly up close and personal if you're sniping then I guess one could say "you're doing it wrong." From the maps we've seen their are barely any spots for suitable sniping. Most of the paths are narrow winding and with SMART thrown into the picture makes everyone a far harder target to hit. While one could "snipe" I guarantee they will not be as efficient as their allies who are working as a team and getting objectives done. While our "Sniper" is raking up kills or "Supporting the team by giving "Covering Fire."
Just once I want a FPS to do hyper realistic sniping, waiting in miserable conditions for hours or days on end, peeing in jars, and not making one sound or else you're dead. Oh and if you're captured you are killed in more horrible ways then other POWs because the enemy calls you a coward. I wonder how many people would snipe then.
Short of some sort of virtual reality, that would basically just become trying to make players avoid sniping because its really boring. Also, law enforcement and urban sniping situations don't require such extremes, its often "sit on this rooftop and wait for permission to shoot."
My only wish is that a game actually requires you to lie prone in order to snipe. standing or even crouching while holding a 30lb gun, where even a half of a degree means your shot is off by a few feet or so, just isn't practical. Nor is using a scope point blank that is intended for at least 100 yards. Get yourself a pair of binoculars, and then try to focus on a wall that's 10 feet away, it cant be done, and that's a much weaker magnification than a scope.
