Essentially everything was a bullet sponge!
I've now tweaked this using http://www.nexusmods.com/fallout4/mods/222/?And its much better.
Its now 1.5x damage out and 2x damage in.
At level 13 most headshots on humans and ghouls kill. 2-3 shots to a limb will maim. Other enemies are still much tougher. 3-5 body shots kill.
Just wondering what everyone else plays at in survival? Trying to find that perfect balance for realism
