Main-Sword/Shield, some damage dealing with Radiant Oppression, knockdown with Piercing Javelin, and armor/spell reduction with Pierce Armor. Quick backup heal with Breath of Life.

Backup-Restoration Staff, main setup for PvP. Current setup allows Rushed Ceremony to be continously cast for long periods of time. Mage Light for increased spell critical, morphed to Radiant Mage Light to support team. Repentance slotted for increased magicka and health recovery, free cast is only really effective in dungeons. Purge to rid debuffs without having to use synergy.

High magicka recovery with some spell cost reduction allows me to Rushed Ceremony for long periods of time. Breath of Life is used for it's speed and increased range, but the increased cost and smaller healing return doesn't make it a long term heal. The heavy armor is almost a must as I am targeted quite often in PvP, as expected. I run Remembrance for the damage reduction, as opposed to Practiced Incantation (be sure to upgrade the Light Weaver passive for the huge bonus in armor)

Currently, I am running 5 pieces of Soulshine (3 Jewelry, all enchanted magicka recovery) and 5 pieces of Twice Born Start, all with divine (the Ritual for the 2nd Mundus Stone). Currently magicka regen is at 1337, this is without drinks.
At VR9, I will be running with updated Soulshine (same as above) and 5 pieces of the Seducer Set, upgraded to purple and reinforced. The added magicka recovery and spell cost reduction should bring me up to about 1700 magicka recovery (this is after quite a bit of testing the math of the game) and make my spells even cheaper allowing me to focus on increased spell power. The extra armor bonus will help me sustain the relentless assaults I get in PvP.
