What the hell? Why not add it back!? "Oh, Azir got hit by the Rylai's changes and, while looking into adding power, we noticed his E's shield scaling was bugged and not working. So, instead of fixing the bug, we removed it entirely. Have a nice day." I mean, it's less that you did it, and more of "Is that it? No more explanation than just, "We removed it,"?"
