There is one small thing that you're missing with the Fist of the Heavens Paladin and that's the fact that Griffon's Eye should never be your endgame goal. Do not waste your time with lightning facets. Look out for a good 2/20 circlet. Though, if you use Fist of the Heavens for your single target boss clearing instead of Holy Bolt, then have at it. I use Holy Bolt personally.
I was the same until I ripped my sin on hc. Dragon flight into a pack of souls with conv aura, didn't even see my health globe drop it just vanished . Now I remade and am getting sleep at least. Getting top of a ladder is really just personal ego and nothing else at the end of the day, no-one else cares
