Ok this perk's leveling has been bothering me. the Head shot kill counter is weak and doesn't work all the time not to mention that you can remove a head and not kill a specimen. It's a horrible way to make that perk level up in my opinion. The requirment either needs a reduction and then some damage added to it or perhaps just headshots?? or something. There are alot of people who want to be sharp shooter but have a feeling that they will never level it up unless they play lifelessy. My friend doesnt even want to play the game anymore because of it. Does anyone else agree this requirment is ridiculous?
