i don't think this will be faster than vwk and i have to say that i strongly doubt that this will work (sry dude

)
The Elite has a long Cooldown and the Smiters will use RoF (revearself of fortune). It will destroy about half of the dmg and heal them for another 80-100 hp.
Because of the high Cooldown they will always have an active RoF so you won't get them down :/
But you could try with the following:
Try to do it with only one running skill and take any of the Crystal Waves (Proph or Factions nvm). It ignores Enchantments for any reason.
I'm not sure if RoC Ends if the Waves are used - if they do you could dmg them with a crystal wave and use the Elite afterwards.

edit: sry didn't read that you already have tested it and that it works

but my hint might work
