Blade dancer doesnt have a perc for it; ive run it before and to my observations it doesnt have one; So i dont run it cuz 1; i try to actually use skill, 2 i hate shotguns in this game, 3 blink is very annoying to use, 4 i prefer playing mid to long range; Its a FPS not a fist fight game And where i got the info depends on what info in question you are inquiring about
