I run 5 Julianos, 3 willpower with spell damage glyphs, Kena divines light, and Torug's pact swords with a restoration staff on my backbar for healing ward and siphon spirit on bosses and to be able to get some magicka back. With the thief stone and magelight im at 70-75% crit depending on what I have slotted, 2600 sp unbuffed, and 1200ish recovery. With heavy chest and medium legs I have decent survivability and pretty decent damage but I can't be too exact because I'm on console so we don't have add ons or numbers.

I have 5x julianos, 2x neriene'th (you know what I mean!) and 3x willpower. all divines, all spelldmg on jewelry and all magicka on armor. currently I have all light armor but I want to go to 1 medium and 1 heavy. I use one fire staff and 1 resto staff. this works verry well in PvE but haven't tested it in PvP. I have 42k max magicka, 900 regen (I don't need much, I never run OOM), 2.7k spelldmg and 75% crit (all unbuffed). this gives verry good dps results and is one of the best builds to do vMA. for skills I use thishttp://www.esohead.com/calculator/skills#1.mczXevk9MW9Mmia8GFts8IPq48IPQe8GUFp8A4hI8GHRG8heqM8IPSd8IfVM8daut8A4hI8A4ub8L7NrkLu8v7GLanX8C7JLzqa6Lzqu6LzqG8D7xrbMz8F7JrzrJ6Lbuy6Lbux8O7arkP6rdeF8zc7zzgeXm8zf7zzNbo8zu7zzHfYE6zHfZd8zG7zzHQ3F8zI7zzJIoX6zJIkL8zN7zzJZcY8zA7zzKpUN8zL7zzK4EX

I use dampen magic, because it gives me a verry big dmg shield (+-20k)
I use mass hysteria cause it's a must have in vMA. I don't use this in dungeons or group content.
I put merciless resolve on my front bar cause then I can easily use the assasin's will and it gives me some extra crit for slotting it.
I use funnel health as main dps skill, cause it heals me for a ton of health (sometimes 8k/tick) and it heals others aswell, you can even be healer and do dmg at the same time, even in veteran dungeons cause you have healing ward. if it gets to hard, slot healing springs on backbar and you are a great healer.

In update 2.3 my ice comet will even hit harder cause of the CP changes.
thanks to soul harvest you can use ice comet a lot in aoe and MA situations, even in single target situations is your ultimate regeneration verry high as a NB.

srry for my crappy english, I'm from Flanders Belgium

Destruction Staff with precise

Inner light- crit and empower with mages guild passives
Merciless Resolve- use in rotation w/ medium weaves
Crippling Grasp- Decent DoT and extra movement speed
Funnel Health- Main spammable and heals group
Elemental Blockade- Great DoT now that we get increased fire damage from cp's
Soul Harvest- 10 ultimate for kill, so we can blow stuff up with Soul Tether

DW Swords with precise (Precise because I'm cheap)

Inner light- for crit and empower on ulti
Twisting Path- decent AoE DoT
Proxy Det- good for AoE and single target
Sap Essence- AoE, heal, and spell power. What else is there to be said?
Impale- ranged finisher
Soul Tether- you will get lots of ultimate from soul harvest, so you will be able to use this a ton. More damage from dw swords as well.

Note: The race for this build will be Dunmer, so being a vampire is viable. More damage towards Destro medium weave as well.
I have been wondering for a while, what crafted armor sets are the best? I am thinking something like 5p Jul with 3-4p Magnus?
