Your toughness is waaaaay to low for GR85. I would build that up. You can do this by putting half your Int Paragon points in Vit. You can also try using in geom instead of aether walker in the cube. This works well for a lot. This may work and it may not as everyone's play style is different, but I would try this out! I have almost the identical setup except I dont have a primal starfire :(, and I cleared GR87. the only difference is that my toughness is at 24M and yours is at 16M
