I realize that at this point I'm pretty much talking to myself, but I've met my goal of beating Hardcore Inferno mode before patch 1.05.

Not sure if this will come through, but here's my character:

Normally I use Soul Harvest and Locust Swarm, but I swapped these for Voodoo and Haunt for the last fight.
I made it to A4 with a group last Monday, but I stopped just before Izual. Then I spent the rest of the week looking for open A4 games, but even now six day's later I've NEVER seen an open public HC game in A4 Inferno. Finally today I created my own A4 Prime Evil game. After running around solo for a while in the Gardens of Hope, a barb joined and we finished the game.
