Build idea : Scion - Chaos ToET

Hello !

Since the reveal of the new Tornado of Elemental Turbulence reveal, I've been thinking of doing a build with it. Here's what I've come up with so far : https://pobb.in/Cffwl04_PGKm

The idea is to lock the skill to lightning, then convert it to chaos.

What do you guys think ? If you have any idea on how to complete/improve it, I'd be more than happy to hear it !
