Rah’binger Witch Hunter was my fav build for a long time. It didn’t hold up to the challenge, as well as Witchblade.
Harbinger set was tested for all classes - Pyro, Witchblade, Sentinel. Conjurer was the best. Fully converted Savagery for 2H is infinitely stronger than any other AAs.
Closest to top20 were the builds that Abuser linked. At first i tried Deceiver Doom Bolt but it also didn’t hold up. The DW gunner is one of the strongest builds that didn’t make the list. It has higher performance than a lot of the builds in the list. Just not as tanky as one would hope.
Also from chaos, Darkblaze Pyro, EoR Sentinel and RA Deceiver scored well.
