There's no doubt that there are some people that can easily take out a formation of bombers usually before they hit their target. From my casual observation, most people can't.
Air Warrior had destroyable Spitfire factories. It was an unpopular feature and was modified and then removed. I fully support your freedom to fly whatever plane you want. Why do you wish to remove that freedom from other players? As others have mentioned, some people fly certain planes because they respect and admire them, not because they are "point and click". If Spitfires were "point and click" they'd have better than a paltry 1.09 K/D wouldn't they? I fly Spits exclusively (I's ,V's, and IX's) because they are beautiful planes and are what defended democracy against darkness in the early part of the war.
I understand your desire for more strategic possibilities. I just wish it could be done without griefing other players. Say, for example, requiring that a certain percentage of a countries factories be down before the other country can win the war.
