do not know which weapon type your ebotdz are in.. but as I can see from your gear your only ias comes from the weapon itself..
if your ebotdz is in a ba then you will reach one more breakpoint whit 15 more ias on consentrate.. 15 (2x) more ias will be useless!!
if it is in a cb then you will need 30 ias to reach next breakpoint whit consentrate...
Remember ONLY ias from the weapon itself will make your ww faster.. meaning you have NO way to change it whitout changing your weapon!
if your dungo is 15 DR% + storm gives 35% then you have 50.. 50% is maximum DR% more is useless.. so no bers..
on a meele char you never go wrong whit 40 ed 15 max jewels

but there are other alternatives..
btw my personal favorite is frenzy barb for pvm whit 20 berzerk (makes physical imunes go down like anything eals using frenzy) + if you use drac gloves on him he is invincible

this char is fast fun and safe for hc considering you kill using berzerk when iron maiden cursed
