I do think it's unfair that you shoot a USR guy and he only has to go half way into an ADS before you are dead.
Divide the USR's ADS time by half and you get it's TTK. Die in 0.2 seconds. Just ridiculous. I can only imagine how broken it is with quickdraw.
The USR is the only OP sniper and it's ADS time needs to be adjusted and slowed.
