I apologize that if I look like a crying baby now, but in all honesty why is this so god damn difficult? Getting 10 head shots in one life is a death sentence, and getting 20 in one round is near impossible. So many times I have tried to get this on Aerodome only to get to 18 out of 20. People aren't the brain dead, unmoving, free head shot kills that DICE expects them to be. I don't know if I'm alone on this, but I genuinely have no problems with every single other challenge in both proficiency and mastery challenges with the other groups of weapons, but for Semi-Autos I'm losing my mind over it. Either DICE tweaks it a bit or when the RPS goes live, I will spread the word to start having servers dedicated to doing this stupid challenge. Again, apologies for sounding like a crying baby to an extent.
