Scion AutoBomber (true one)

Hello there.
In the footsteps of this build https://www.pathofexile.com/forum/view-thread/2231173 i've created my own double herald autobomber scion.

Glasscannon version (3kk dmg/5k es)

A bit more tanky (1.2kk dmg/7k es)

Guys, i need your advice, how to improve dmg in GC version up to 5kk and not lose all ES?
