Stutter stepping is, in my opinion, the result of poor planning of class skills on Blizzard's part. If wizards had a reliable kiting skill that didn't have to take more than 8 seconds to cool down, then most likely, there wouldn't be the need to stutter step almost all the time (I have very early carpal tunnel so stutter stepping a decent amount aggravates it).
Stutter stepping is actually to reset your attack animation so you attack more often in a shorter time. More time attacking = more damage done = shorter fight.
Except this is wrong as you do not shoot any faster no matter how hard you stutter step.
