If you mean unique mostly by the E, then I am afraid to say that, beyond looking cool in-game, if the sole puporse is to avoid the projectiles is then but a poorman's Windwall/Unbreakable, and is the same reason Riot hasn't implemented it (They even thought to give such to Zilean in his rework, but came to the same conclusion previously exposed).
