Flank argument, have you tried to shoot someone's head across a map. Unless you have AA its not that easy. Not to mention glint makes you by default a target and i have counter sniped snipers with almost every gun in the game, except the shotgun (don't play assault) and pistol (takes too long) more likely to get head shot.
2nd, the reason y recon class likes to camp its because we are not effective at stealth (glint again). Recon is not effective in tight corners y rather cover the street next to the base we are stealing and counter flanking then sit there with a pistol sinse i already placed the motion sensor (give up easy points but I'm more useful)
I like a challenge and body shots don't always kill, I would prefer they exaggerate bullet drop so it takes more skill then point and shot ( i agree with you guys on this), they are removing the beacon from recon so the camping problem should lessen but I wish they give it to the medic instead.
Not sure how I feel about the sweet spot, quite sure everyone has but I think i would prefer they added that as a different type of ammo (critical hit), that way you'll you to weight your option.
