As long as I have played freezetag on XI servers, yes, there is more sway to the sniper rifles than in normal servers. Using the Steady Cam attachment helps, but only for targets that aren't moving. Any kind of lateral movement, and you can't hit them, whether leading your target or not. The Hunter Killer or Iron Lungs perk helps because it gives you more time to hold your breath. The old MW2 mod allowed you to use Hunter Killer and Stealth, which I would combine with my favorite Sniper Rifle, the Silenced Intervention, but now both Stealth and Hunter Killer are the same perk, and it takes almost your entire breath to steady your crosshair, so it is annoying. Hunter Killer is a great perk, but being targeted by UAV, Predator Missiles, Smartbomb, etc, has pushed the stealthy snipers into extinction.
