I understand the argument you would bring up, but I personally have issues with those mechanics. My ability to maintain the crosshair on the head of a moving target, or while I'm straffing, (even in an ADS scenario) should outweigh a person who can't. I feel like bullet drop is one of those mechanics that allows a player to land a hit they shouldn't have. What I mean is say a player is sniping a fast moving target and they are having all sorts of trouble getting precisely on the head, but in one of the attempts of trying to hit the head they had pulled the trigger above the head only to have luckily had bullet drop sink the bullet into the skull. Meanwhile, without bullet drop you have to fire when the crosshair is on the same y-axis as the head every time no matter what. I don't know... i understand in a target practice scenario bullet drop adds to the increased skill curve... but in my opinion, in a first person shooter PVP experience, there is tons of straffing, jumping, crouching/prone, etc. etc. that - in my opinion - requires the user to have more precision to keep the crosshair at the head than otherwise.
