Legolas shooting stuff....

Nope. It would still be much easier to shoot the opponent through the throat. In the case of the Orcs, they don't have armor over their throats. They have armor in all the other places.

I think the history of warfare shows this not to be the case. Besides which if you have powerful enough a bow, like the English longbow for example, then the presence of armour is of less concern. The arrows will still be deadly at medium to short range.

In large scale battles an archer is not likely to target a specific body part, apart from maybe the centre of the body. Rate of fire is more important in that scenario than accuracy and aiming at the throat all the time would reduce that rate of fire.

Further to even be comfortably sure of hitting the throat you would need to be at quite close range, and as already described, the armour is less of an issue then. Far better to aim for a target that you are at least 5 times more likely to hit (on surface area alone), if you do hit it will nearly always puncture a vital organ and at the least incapacitate the man, and if you miss still has a good chance of hitting the legs, arms or head.
