Point blank archer?

I'm trying out this build i'm wondering what you guys think of it? What do i need to add and such.
I'm using fire arrow and frenzy as my main damage dealers. Fire arrow being linked to multiple projectiles and the rest of the support gems being standard end game stuff like grace,enfeeble etc.

Soooo what do you guys think? Can it work?

Passive skill tree build

Oh yeah also if i need intelligence for a skill gem, the build is around multiple +30 intelligence nodes so that's not a problem.

Burning Arrow isn't the best multi-target around...tree doesn't look horrible, it'll clear to merc at any rate.
