Azir's Tower cannot reach around nexus in twisted treeline

In twisted treeline, if an inhib is down and azir puts his tower up in place of the nexus turret, it cannot reach the other side of the nexus where players are safe to take it without being targeted by the turret.

Can we increase the range of Azir's turret in TT so that enemy players can be hit by the turret from any point around the nexus, if not only melee range.

Otherwise i feel it defeats the purpose of a turret if it can't defend nexus on its own.
