Trying to figure out how to make my barb more effective in T6 rifts without using the unity trick. I was about to switch to physical and do the reakors with rend build but they nerfed rend back to uselessness. Right now i can get through the rifts (between 10-20 mins) but run into issues with some mobs (mostly electric, molten, and damage reflect). I am starting to wonder if the IK set i use is the best option...but don't know where to go from here and any advise would be helpful. Other then getting my ammy to have +to fire skills instead of average damage i'm kinda lost.
