this is the build i would have http://us.battle.net...SUjQ!gcS!baaccc
You will notice that-
Hungry arrow will generate my hatred. With the added pierce i should get Hatred up really quick.
Rapid fire is the boss killer move that slows the boss (cull of the weak and mark of death will help too).
Multishot is my AoE that also regenerates my Disc so i can keep shadow power up.
Shadow power for the increased attack speed and dodge. I may change the rune if need be.
Sentry gun for added firepower although at higher difficulties i may have to change to a defensive skill.
and lastly mark of death for extra dmg. This can also be changed out for a defensive skill.
This build is for PVE and will be used with groups hence why i dont have Vault or evasive fire as i shouldnt be getting hit much.
Let me know what u think.
