I have to admit: Now that I think back, Vulcan has hit it on the nail. NOW I have more options, I can pick and choose my attack based on the circumstances. Before? Drones warped so badly that you could never be sure when you got to that "fire the guns" moment they'd even be there or would have jumped up, down, back, fore, or any combination thereof. Hitting the lead was the only way to actively track and lead a target, so at that time, you always aimed for the lead.
Not a social decision, but a limitation of the gameplay. Since then? Some of that's ingrained in the brain and some of it is concious choice. But that's definitely where it came from for me and many others.
