[2.2 Theorycraft] Shadow-Assasin Obliteration Wander? [Help Needed)

Hey guys I thought about a Wander build which utilizes the new unique Obliteration. here is the tree

I could really need some feedback since i havent played a wander yet xD

thought about using kinetic blast as main skill and the vaal power siphon to clear screens... mb herald of thunder to go assasins mark and get 100% crit? dont know just a rough concept

I´m not the best at math but only with the basic skilltree and the weapon itself I think it would be an average dmg of 64704,3936 without the cosideration which dmg modifiers/skills i use...

would be cool if some1 look over the numbers... :D
heres the spreadsheet

bump...
any wanders around here who could help me xD
