Names: Gunslinger, Agent, Pistoleer, Handgunner, Small Arms Expert, Officer, ... Pistol Survivalist lol?
And powers (at level 6):
1) 70% Pistol discount
2) 50% Pistol damage
3) 50% Pistol reload speed
4) 60% Pistol "Run n Gun" bonus (Reduction in weaponswaying when moving + reduction in speed penalty while ironsighting)
5) 40% General recoil bonus
6) 50% Faster weapon switching
7) ZED time reflexes (During ZED time, your reload bonus goes up by 1.5x, your recoil bonus 2x, movement speed increases by 15%, double draw speed and all semi-auto pistols become full-auto (no need to click each shot)
8) 80% Visionblur resistance (less screen-shaking etc from vision-blurring attacks etc)
Levelling requirements:
1) Pistol damage
2) Multiple ideas here:
a) Consecutive pistol kills (kills with pistols done within max 2 secs of eachother)
b) ZED time pistol kills
c) Pistol style kills (both a and b together!)
Just some thoughts
