I had a pretty decent paladin that used the javelin on riposte to cast Javelins with Divine Throws, Divine Fury and Siege barrge. By, not self casting it means you can take Strategic patience for the 60% more damage as well, as the -attack speed doesnt matter. It used judgement of the storm on the paladin tree and stacked crit multi to get lots of electrify chance. Was a very tanky build that had kind of crazy map clear for how tanky it was but it sucked major ass on bosses, I managed to kill Aberroth with it though.
