My gear setup is not completely optimal. The optimal setup would include a 8% CDR/Fire/Elite/Socket Soj in place of RoRG, then you would have to use the Raekor Helm instead of Leoric's. Then you also need an 8% CDR Unity as well in the other slot. The optimal neck for this setup would be an incredibly well rolled Flavor of Time for the extra CD on the neck instead of from the Leoric's Crown. This would result in a large damage boost, but seeing as Soj's and Unity's are already very rare it is unlikely you will every find both with the proper rolls.

Helm - Leoric's Crown is the only real choice here, Lots of CDR! Optimal secondary is lightning/fire resist.

Amulet - My amulet is not optimal, Instead of Vit I would have preferred 20% fire Damage or Strength next. Optimal secondary is lightning/fire resist. Obviously I would rather have a Fire/Lightning Immunity Amulet. Never found one. EDIT: I have since changed to Fire/CHC/CHD/Socket Squirts for more DPS.

Shoulders - My Vile Wards are probably the most optimal for HC, you could swap out the All Res for Furious Charge Damage and try to get fire/lightning secondary. I'm not sure I would recommend dropping All Res for FC damage since Vile Wards already give so much of it, it would really only help on ST slightly.

Chest - You could swap out the All Res for Elite Damage Reduction, which with as much resist as we are getting from gems, it is certainly more damage reduction from champs over resists. Melee/Ranged reduction secondaries are useful, but are somewhat inefficient with this build since most mobs will be permafrozen from your charge. Fire/Lightning resists very useful since fire chains and electrified obviously do damage even when the mobs are stunned/frozen. EDIT: I have changed my mind, Ranged reduction is VERY useful since ranged white mobs are probably the most dangerous thing in the game other than Fire Chains 5 packs.

Gloves - Str/CHC/CHD/CDR, Fire/Lightning resist. You can sacrifice one of them for Vit if you really need it, I would not recommend it though.

Belt - I got very lucky with this one. Str/Vit/Res/%Life. 4-6 second increase to Ignore Pain, with this 6 second roll and 15 stacked gogok, I have ~94% Ignore Pain uptime. RIDICULOUS!

Rings - Unity with Invincible follower required for us melee on anything past 25 Grift to be safe. RoRG required to keep 5 Set Raekor and use Vile Ward with Leoric's. I would use a Fire Soj with a socket instead of Unity if playing in a party.

Bracers - As I said earlier I use Krelm's just because it is HC and having your Charge interrupted could spell death. Also fuck Vortex into Molten/Frozen. EDIT: With such high Ignore Pain uptime (~95%) I have decided to switch to Strongarms for the sizable DPS increase.

Pants - Standard Str/Vit/Res/sockets. If you can't get All Res shoot for fire/lightning with Armor.

Boots - Standard Str/Vit/Res. I'm still not sure if it is worth it to roll the Movement speed off of boots towards 400 armor for a bit more defense in sacrifice of Paragon points into Movement speed.

Weapon - One thing I didn't mention was that with Stalgard's you have one primary that is not taken up with Fire damage like Maximus. This means you can get Vit or % Damage. Mine has vit for now, If I find another one with a good damage roll I might drop the vit since I am at 600k HP.
