I have yet to have found a better 1v1 build.
The idea here is to stack Health to increase the effectiveness of Dark Cloak & Spiked Bone Shield
These two abilities can out sustain huge amounts of damage, death will only occur once Stamina & Magica is depleted. For this reason most damage should come from Light Attacks, while pooling resources.

Bar 1 = Magicka & Melee
1: Siphoning Attacks - Mana returns & Heals
2: Sap Essence - Damage boost for both Spell and Weapon
3: Crippling Grasp - Gap closer / Kiting
4: Dark Cloak - Huge value, refresh every 3 sec
5: Mass Hysteria - Minor Maim & AoE CC
6: Incapacitating Strike - The best overall PvP ability in the game

Bar 2 = Stamina & Range
1: Relentless Focus - High Value for damage & stamina regen
2: Lethal Arrow - Major Defile
3: Draining Shot - Knockback, Stun & Heal
4: Spiked Bone Shield - Huge value, keep active
5: Resolving Vigor - Out of combat / team heal
6: Toxic Barrage - Burst & CC immunity.

Gear: Shalidor's Curse & Grace of Gloom

If you found this build useful, give it a like so others can see it too.
