Based on what I was seeing other people build and what I could gather about her abilities. I decided to do a mostly positive build. Doing so with the minimum amount of format I got a 4 forma build.

Physique - Increase Base Health or Rejuvenation for HP recovery on top on Mending.
Primed Continuity + Augur Message - Duration
Stretch - Range
Adaptation + Arcane Gaurdian - Damage Reduction/Survivability
Umbral Vitality + Intensify + Power Drift - Health/Power Strength (bonus from umbral's and max 90% reduction for more survivability)
Mending Splinters - Health Recovery/ Stack with Rejuvenation for never-ending HP.
Hunter Adrenaline + Arcane Energise - Almost never-ending energy.

I could go for a neg efficiency because of Energise at low levels and the high energy pool this has at higher level mobs that can hit above the armour and damage reduction. But if I'm caught in a pinch, someone falls, or I want to spam I decided to leave efficiency at 100%.

So far this is working for me after I finish I'm taking it to the SP to try it out.
