Bow Mara build viable?

Hey guys, I'm working on a bow build for a marauder. I'm kind of clueless here. Is this build going to have the damage output and life to get through merciless? Anything I missed? Anything I should have skipped? Thanks all for advice.

No one?

Marauder can pretty much do any kind of build well, except CI or Vaal Pact builds.

There's a bow build thread here:

Ah thanks. This is similar to what I was thinking. Just done a lot better. Thanks.

warning: shameless self-promotion xD

might also want to have a look at my post from a few days ago where I made a writeup of my experience with point blank.
