The main advantage of this build vs the previous earth ones is less about the speed improvement and more about how it kills through Dark Hour. This means you no longer have to worry about accidentally overdamaging and whiffing because of the full dispel.
I only have one Heldenhymne, maybe with two you cut one of the Pillardrivers and that lets you cut some buttons? Not sure. You can probably cut either Narmaya 2 or Lobelia 4 as well if you have more perps or better artifacts.
