I was thinking about using this build:

It is meant for group PvP, not solo. I will depend on others for my defense while laying down the maximum amount of pain.
It's very focused on destruction, with a mage ultimate and just one dark spell.
This build should give me high single target damage (Elemental Susceptibility -> fire destruction staff / destructive clench) as well as very strong pbAoE damage by using the other 3 abilities combined with the ultimate.
The thing I am worried most about is the high stamina costs and high vulnerability.
I'm considering using medium armor over light armor, in order to gain the stamina bonus and to be a bit more beefy.
What do you reckon?
