Started over given the changes that happened 9/23:
The Comebackian: Now that I've had some time watching the beta and how certain skill work, interact and have a inkling of how combat might progress, I've come up with my final draft pre-playthrough for my hardcore toon, The Comebackian. Allowing for the learning of hardcore play, this monk build ensures that short of truly tremendous lag spikes or a blatant disregard for your situation, you should be able to tell a "Whew, that was close!" story as you learn what is dangerous and what is not. More versatile than Patches was, and more refined than the my initial tank build, this setup values mobility, cc and high spirit builder dps to fuel your exploits. The Near Death passive is for one-shots and massive mistakes with Obsidian Serenity to right use after, ensuring you really don't die. Alabaster Lethal Decoy is what you primarily use to ensure you don't lose your toon when you can anticipate bad stuff ™. Your primary attacks give you cc/mobility (Alabaster Dashing Strike), range (Indigo Deadly Reach) and cc/debuffing (Obsidian Dashing Wave). Finally, Golden Matra of Conviction heals on average 961 HP per target hit, meaning you should even be able to regen on immunity shields and recover from a Near Death experience quickly.

Ye Olde Ballistic Archer: Not much to say really. Snare everything, blow up groups with Rocket-fueled Strafe & single targets with Rocket-fueled Rapid Fire. Keep away from your targets with Surge, and if things really go to hell, vanish with Lingering Fog. A note on weapons: 2H Crossbows, given the speed boosts in the build, should be favored, given their tight damage range, IMO.

Trollblood Hemomancer v2: I have no idea why, really, I love Blood Ritual (and the Bloody Trinity of Ritual + Pierce the Veil + Life Link Handler Puppies) but I really do. I truly hope *NO ONE* ever tries this build except me, as there's no way it's not destined for failure... but <3... I want a challenge
You use Mass Confusion & Zombie Dogs to keep things off of you, with Gargantuan for emergencies. Soul Harvest is to keep you healthy and boost your damage to acceptable levels. Firebomb & Haunt are for something to do.. or they might actually be good

The Tough: Modeled after a warrior tank in WoW (something I know *NOTHING* about), this is a group Inferno tank build meant to protect your friends by protecting yourself and keeping the baddies on you. I can't imagine a scenario where you would use this by yourself, as your gearing will be focused on resistances, armor, vitality and your skills provide little damage. Depending on the encounter, Obsidian (for +80% all resistances) or Alabaster (for +50% life & regen) War Cry and your available resistance gear, should be swapped. Also, Golden Frenzy (Smite!) can replace Indigo Cleave for single boss encounters.

For Blowing Things Up: Nothing special, just a generalist Wizard nuker/farmer. Electrocute for crowds, Ray of Frost for extreme single target obliteration, Wave of Force for a strong active defense, Wormhole for farming and quick escapes, Ancient Guardian so you don't have to reroll (can be recast before the previous one runs out of charges, extending your 'life' until you can escape or kill) and Power of the Storm Armor for -7 AP/s to sustain RoF/Teleport Spam.
