Light Armor lvl 80 what stats?
S/d is moar in Conditions via fire/earth skills that leave BURN/BLEED.
Try set with Power/Precision/Condition as pure glass canon or Carrion Set(Power/Vit/Condition) with Clerics jewelry(Power/Toughnes/Healing). You shuld think about changing traits to 0/0/30/20/20, it will give you moar survivability(toughness from earth) and bigger conditions dmg.
glass canon is out of the question.
That might work, need 30 in arcane for dodge roll healing, using a lot of support and healing for instances, works rly good atm.
Just gear i am concerned about.
From the sound of it you might like clerics set? Power/toughness/healing. Maybe mix in some gear with vitality and condition damage too?
My advice is to go to the heart of the mists and play some matches with your build using different amulets to get a better feel for which stats work best for you.
