I didn't pay attention but for your Volatile Reversal, you will need to get cooldown recovery on your boots&belt and remove thoses points in Traveller's frailty. I think it's mandatory. +30% damage taken is okay at start, but at some point it is not viable anymore.
And for the Julra's ring, you can trigger the movement with the rush on flag, u stun just after with shield bash so u are safe from the +25% damage taken from Hammer&Anvil stance, but ready for the big damage ! (special bosses, in map you don't care about all this, stay in hammer stance -25% damage taken)
Enjoy the build, i think it is one of the strongest (if not the strongest tbh) of the game. you can get 10Mdps easy and perma stun on bosses... and julra's rings is the easiest legendary to get in the game
