Yes lets give everyone a Rocket launcher because I want faster kill times.. *insert rollyeyes here*
All I read from the people who want more shots to take someone down is "I suck at Halo and aiming, so the more shots it takes to kill, the longer I can stay alive".
3Shot Pistol, 4shot BR or the 5shot DMR I can win a fight. I just want the game to finally let us do more damage if shooting at the head regardless of it being an AR or hell even a Spiker. Why should someone who is spraying the AR win a fight versus who is aiming and shooting at the head.
I don't understand your issue. Are you saying headshot should do more damage to shields as well? I disagree. The sandbox is fairly balanced with respect to taking down shields and damage to health. Furthermore, you would have a time trying to justify allowing the AR to headshot capable, considering that the player has no direct control over bullet placement, leading to the same furor that bloom caused.
