It can perform really solid for builds like shockadins/freezadins with bundles of facets if you can get your hands on enough. All those sockets plugged up with the appropriate facet type gives you good resist penetration, and double benefits on the +% elemental damage as well (same as enchant and fire mastery or venom and +% poison damage). The weapon can reach the last zeal breakpoints with some IAS jewels or shaels (need 142 IAS total - 40 comes on the weapon, subtract any you get from gloves or amulet and the rest needs to come from the sockets) and provides decent physical damage. I imagine it could be good for normal zealots as well, again because it has ok mods to start and you get to load up the sockets with damage jewels, probably mostly +max jewels outside of the weapon.
