Where is it? Why not just model the sniper realistically and give him sufficient ammo? Afterall, its a realistic game. And the only reason to limit his ammo is because hes too powerful in some way. Make them more expensive?
I know its important for a sniper to relocate and not fire off a thousand rounds from the same spot, but cant that be modelled differently? And does that even matter really considering a rifle squad can fire outa the same spot continuously at long range and not get IDd?
Or was there some secret rule in the past where a sniper could only fire 10 rounds whether he was in an extremely good position or not?
