I may or may not be right but if I were you, this are the changes I'd make
Shoulders - Haunt % to CDR (i prefer higher CDR so I can spirit walk more often)
Ammy - Find one of those elemental ammy (countess julia, etc - preferred is lightning one), with socket and CC (i'm still looking for one)
Ring - your SOJ too bad didn't get poison dmg but try rerolling fire dmg to socket
Pants - Firebomb change to haunt or something else you use more often.. haunt or piranhas
Legendary gems are awesome:-
Top Tier
- Bane of Trapped
- Gem of Efficacious Toxin
This is what I've understood after playing primarily my WD the entire Season 2..
playing Jade-WD need to follow skill sequence ( haunt + locust + pirahnas > soul harvest) kinda troublesome cannot simply spam skills
