Archer/Hunter Help Return to Ether Sharpshooter Build Critique

Just want to get critique on my build here.

Some Notes:
The goal was to go all in on sharpshooter bc i like the playstyle, and keep it spell spam with no mythics (im broke). I'm aware ornate shadow cowl can be replaced with morph stardust for better ehp and only a bit less damage, but i like purple so i wanted an ornate piece. Also chose return to ether bc i think pre-2.0 made me see all of the olily that i want to for the rest of ever.
IMPORTANT: Ignore my tomes, I just put what i have because im a pretty casual player with no groups so they are all i have since ive barely touched raids. also FORGET ARROW BOMB, its cringe and i spam phantom for focus.
I find having high focus very successful (Crepray 87k dps), maybe a little soft for some people in terms of hp but ive always been a glass cannon guy.

 

i made a similar build to your's but i cant sustain the focus consistently, any advices on that?

sharpshooter is very hard to play

 

Its def harder than a boltslinger build would be, but I like the challenge personally. Anyhow, the Grape Bomb tends to harm focus builds, since missing the three offshoot arrows resets it, making arrow bomb harmful for your dps. I tend to go with CrepRay instead since I get 38k dps out of it with no focus, which is higher than even a full phantom ray would do every second it is active, which can be for like 7 seconds assuming you have full focus.
