The ability to control such wide portions of the map with his ultimate is far too powerful playmaking and since it denies any counterplay aside from avoiding the zone in the first place, I doubt we'll ever see anything like this in League, thank God.

Having a mini-Azir ult as a basic spell is already far too unforgiving. The fact that the walls last 60 seconds (to Emperor's Divide's 5/6/7 seconds) also means you can simply go mid lane, capture this point and lock your opponent at his turret. Or you could lock jungle monsters while you kill them with ranged autoattacks. Stuff like this only belongs on an ultimate.
