For you wizards, this build is absolutely amazing now that Energy Twister procs Critical Mass like crazy again (seems like it was stealth un-nerfed in 1.03).

You can basically just run into melee, cast Diamond Skin, spam twisters on the mobs, and then blade spam. You'll find you'll have near 100% up time on Diamond Skin. I also found Teleport to be superior to Frost Nova cause your main weakness are the same affixes that trouble other melee -- Desecration/Plagued + Jailer, Arcane Sentries, Frozen Orbs, etc. Frost Nova really doesn't help deal with any of those, especially when it only lasts like half a second on elites. Better to have Teleport as a backup, and just like with Diamond Skin, you'll find the cooldown up quite often because of critical mass. Since you're not kiting or don't really need distractions, I chose Safe Passage over the more popular Fracture/Wormhole.
I don't even have much LoH but this spec is tearing shit up. Archon for tearing up regular mobs, and Twister/Diamond Skin spam for elites.
I'd say you'll want at least 20% or so crit, gear with some AP on crit for more Twister spam, and good resists (since Prismatic Armor would be greater than Force when relying on Diamond Skin).
