Azir Nerfs on the PBE

Quick little note, I don't understand the azir balance ideas work. You take away some of his soldiers' damage, and possibly a good chunk of their range, and in turn shift it to a slight change in base AD. I understand he needs a slight nerf, but if I were to think of one stat that is completely irrelevant as Azir, it's base AD. His autos are from his soldiers, none of his spells have any AD scalings, an azir using his own autos is not using his kit to its full potential.
