Witch Doctor in Season 34

Hello all.

This season will be my first time playing WD, and right now i am aiming for that Helltooth Garg build.

As i have no idea about WD items and the class overall, i would love to hear your suggestions on this.

Which build should i have to comfortably farm Greater Rift level 90s - 100s?

I saw the SOLO PUSH tier list and builds but i have no idea which build should i use to farm items and exp.

What would your suggestion be? Thanks in advance.
