Archer/Hunter Improving My Build Or Looking For A Better One (no Mythics)

Hi! Here's my current build https://wynndata.tk/s/cv1jfm I wanted to have a high DPS + spell spam type build but I seem to have poor sustainability when soloing EO. Any advice will be helpful thanks!

 

what is meant by sustainability here? rainbow aside i don't see anything particularly wrong with the build.

 

probably both mana and health sustain
only like 40 health regen, and only 7 mana regen with nighthawk

 

hpr is a myth
i assumed 7mr is fine for 1/1 spell costs, is olily an exception?

 

it isn't a bad build by any means.
if you want tanky and sustain you're gonna be losing damage.

 

nighthawk is an exception, at least at decent click speeds
