Here is mine posted recently : (1.3.0.8) Reaver - Wereraven/Blade spirit Guide (SR36)
That wereraven is really not squishy ^^
I checked your buid I think you spread a bit too much into damage spell Wereraven/Devastation/Olexa/Trozan.
At least from what I tested having wereraven 26/16 and glacial talons 22/12 + Any cold spell work wonder. (if you want to use wereraven most of the time ofc)
I think with evoker that weapon can be quite good :
But I dont have a evoker yet to test he is currently leveling ^^
Wanted to try the aether wereraven but it seems cold wereraven have a lot of possibility with evoker too.
