Here's my current skill setup:
Shock Pulse (Piercing Orb)
Disintegrate (Chaos Nexus)
Diamond Skin (Crystal Shell)
Energy Armor (Prismatic Armor)
Teleport (Safe Passage)
Archon (been toying with which rune, mostly Improved Archon but recently I've been using Slow Time for more survivability while in Archon)
Astral Presence (to support Disintegrate)
I know A LOT of people don't like using Disintegrate, and those that do don't seem to like Chaos Nexus, but I personally love it for speeding through weaker trash packs. That being said it is a lot weaker on those champ packs (since you need to kite most) which is what inferno seems to be all about, so I'll probably switch this out soon.
I've been wanting to put blizzard in my build, and I've been considering dropping Disintegrate for it and just using Shock Pulse as my primary damage source. Any suggestions?
Anyway, what have you been using?
