Have you done plane of hate and fear? Hate would probably net some good gear for you and the pet especially if you're able to do the south part of the zone as its somewhat out of era but not super OP and was released at the launch of THJ.
Yeah would think that is doable. Vox is easier but getting fearless, rage of rallos and the warrior AA that makes you start healing when under..30% health? Would be good. Rage of rallos and some good proc weapons usually rips through them.
