https://www.youtube.com/watch?v=WYi_UPe0LWcQuick video showing what a decently geared lightning monk is capable of, I've been able to consistently clear T1-T2 rifts in sub 10 minutes now since I've acquired SoH..
I'm missing a fire SoJ still for my fire set, but I have all of the other mandatory fire pieces (GnK, devastator plan, burning axe, trifecta magefist, etc) so I think I'm going to take my other 70 monk and fool around with fire to really see the comparison between the 2 builds. As of now I'm really really loving the lightning monk though. I have to do some testing between WKL + SoH, or Fulminator + SoH, but the double proc on Fulminator + SoH is making clearing extremely easy. I was doing T4 rifts in about 15 minutes earlier solo, but I need to bump my toughness up a bit before I feel more comfortable in T4. Only currently have 10.5m toughness with about 20k healing - some affix are definitely nasty in the higher torments.
