first D4 build

This is my first D4 build and I am after feedback. I was following the maxroll rain of arrows build but got 2 mythic and tried to make my own build. I Unsure if I should keep going with my own build or salvage my mythics and go for shroud of false death, I am pretty close to having the runes. but I don't want to destroy the mythics if the bump isn't worth it. any help is really appreciated.
