Are you looking for a build that uses the cooldown version of Stun Jacks or do you want to spam them with the transmuter, Quick Jacks? What about element? Is lightning strictly required or are you ok with conversions?
There the Harra set and the Light’s Guardian set for endgame support you can build towards, and Light’s Guardian even has a lower level version to use for Elite difficulty. There’s also some converted versions like Chaos or Aether, though those are only available in the lategame, as well as builds using the CD version for the Electrocute damage, like this one. Stun Jacks is definitely a way you can go and you have plenty of options to choose from. Elementalists, Purifiers, Sorcerers and who knows what else are all an option. And Stun Jack item support is about to get even better next patch.
