Crying stormtrooper

People make fun of them for their aim, but have they ever worn one of those masks?!? You can't SEE XD

The early clone troopers (let's say Attack of the Clones or Clone Wars TV,) are much better shots than, let's say, New Hope troopers.
I theorize, when the Empire stopped using clones and switched to drafting guys, the training programs went away and they just handled the recruits armour & a gun. If they consider the storm troopers expendable, they may not be teaching them the proper way to handle a blaster?

Well, believe me, I've got to try on a stormtrooper helmet that someone was making, and you can't see anything more than a foot in front of you XD

The empire didn't think that one thru. If you can't see you'll have trouble with all your stormtrooper tasks!
