Sniper rifle fix please

[Nism100]

The snipers are good and I like the effect of seeing the view outside the scope instead of like other games, but what I don't like is the way that;
1) it is too hard to move as it's sensitivity is too low and raising my sensitivity will mean I will screw up with other guns.
2) There isnt enough sniper spots on some maps
3) Hitting moving enemies is so annoying.
4) There's only 1 space.
5) It seems to either give off loads of gun smoke or the loudest bang as it's always really clear where they are.

Just making usage and adding either more sniper spots on new maps or adding them to the old ones
