Auto attacks nerf

I understand wanting to get rid of the whole orb walking, animation cancellation that allows you to get off more attacks.... But why is it that now auto attacks will literally die in the air on the way to their target... seems a bit excessive. It's to the point where I can auto see it hit and hear the attack land, but if I start to move too early it literally does NOTHING. Can I have a slight explanation as to why this has become such an impossible mechanic to leave in the game?
