High DPS, Two-handed DK w/ self healing abilities AND an AoE, Destruction Staff Dk with astonishing mob grinding abilities.

5 Medium Armor and 2 Light Armor, with Two-Handed Weapon. Great damage per second if used right.
Charge with Stampede (high chance on critical hit), immobilizing enemy for 3.5 seconds, and then hit them with Flame Lash. A powerful attack dealing crazy damage, and even crazier damage vs. targets either stunned or immobilized, while also healing you. And for the next enemy, hit with Wrecking Blow, stunning enemy for 3.5 seconds and knocking them back AND increasing the power of your next attack by 46. Then either use Stampede, followed by Flame Lash to certainly finish off your enemy- or use Reverse Slice after activating Wrecking Blow instead. Dealing a moderate amount of damage, with extra damage increasing based on target's health loss, up to name maximum of 300%. Which will easily devestate any enemy if used after Wrecking Blow, considering its effect. And left with one of the most helpful abilities, Green Dragon Blood. Helpful in any situation when your health drops, with a bonus effect of increasing health AND stamina regeneration.Seems simple yet diverse, and also fun for leveling to me. Couldn't decide on an ULT, so I just went for my personal favorite. Feel free to use whatever ULT you would like.
And for the secondary spec, I went with a destruction staff fitted with AoE abilities. Able to grind giant mobs remarkably easily if used with sense.
Walk up to your mob of choice, set down Elemental Blockade for a DOT AoE power, trap your enemies with Burning Talons to keep them in place of Elemental Blockade while doing DOT, and then hit them with Engulfing Flames. Your enemies are bound to die soon enough, but if you want to finish them off you can pick them off with your staff.
And since this character's role will be focused on stamina based abilities, feel free to finish your enemies off with either Draw Essence (an AoE ability absorbing your enemies health and restoring part of your magicka too), or Sea of Flames (an AoE ability causing damage with a cost of a lot of manager per second, but restores a great amount of your mana if the ability kills one or more of your targets). With each of these two AoE abilities, you really don't have to focus any of your skill points in magicka, letting you put them in stamina and/or health. And lastly set with Standard of Might, one of the most powerful ULTs in the game, let alone an AoE ability- this ULT was hands down the best for this spec.
And that's my character suggestion I might be using during launch. Hope you enjoyed!
