If you want to level with the “Voldrak” weapon i would just go Savagery/Upheavel build without werewolf. There is no phys RR in both masteries, so it will be rather difficult to farm endgame as a physical build. Focus more on bleed damage and you should be fine using “Troll Bonecrusher” as a weapon. Bleed RR is on both masteries.
You are level 36 come back when you are around the 70ies for feedback again. Focus on pierce and bleeding damage as of now. Here your lvl 36 Grimtool, i ve taken all the cold damage skills out and progressed towards the “exclusive skill”. Take “Ghoul” as a devotion as a safeguard when you drop low.
Here are some endgame primalists from the theorycraft thread:
Fenris pierce by romanN1 (werewolf)
Jarldin Fury bleeding by Legrad (non-wereform)
Eldrun lightning by _maverick (wereraven)
You could end up with something similar to these guys
