I use a javazon with maxed lightning fury. I use etheral titans and gear that adds to IAS, upgraded Twitch 20% IAS and other nice stats, Bood Gloves, 20% IAS - 3% Life Steal - 7% Crushing Blow - 25% MF, Shako, Gore Riders.
I can clean house very fast and effectively at clvl 83 and I have a lvl 83 Offensive Merc that adds to my damage (merc is doing 1.8k). Anything that is not lightning immune goes down faster than you can spit. And with all the IAS equipment I have and maxed out jab and aura from merc the LI's are really no threat or a problem.
I also usually do Diablo runs as I find he's the easiest to do now. Setup is always the same and I just target the Oblivion Knights with LF right away before they can cast IM on my minions. Once everyone is cleared I just get right into Diablo's Belly and jab him to death. My chance to hit him is quite high and I hardly take any damage at all. Oh btw, my resists are -70 to fire, cold & poison and -20% to lightning ...

I rarely ever die and usually its just because I'm trying to go too fast.
Best thing I like about doing Hell Diablo runs, no "BURNING SOULS"!
