DH is a total powerhouse. Both Maurader's and Unhallowed are wicked sets. Just depends what kinda playstyle you like. I played the Unhallowed build and found it pretty fun. best way to do it is get the full 6 piece set, hellfire amulet, restraint / focus for rings and wear Yang's recurve (has +50% multishot dmg) and Dead man's legacy quiv (enemies below life% are hit twice by multi)
Then in cube use calamity (enemies are marked for death) , cindercoat (30% reduce resource for fire) and Convention of elements.
I'm basically just quoting Deadset's build on Icy Vein's. This guy has some pretty wicked builds:
