Chaos/Vitality Witch Hunter Help

Hey all,

Im pretty new to the game. And after a few days playing my first toon, a Conjurer, i now want to try a melee class.

Dont know why, but i really like the idea of a Chaos Witch Hunter.

I started theorycrafting with the Grimtools site but im pretty bad at it. It is my first try:undecided:
And i know that the items, especially the green ones, are unreachable for me to get. For the Devotions i dont really know what to take too.:confused:

I hope you can help me and have better ideas/builds.
Even when the Items are hard to get. i want a viable strong build that i can work on to reach, someday:)

Sry for my bad englisch:o
