I can roll off the socket for %damage though.
The guide in the link I posted recommends STR, VIT, CDR and socket. Perfect gear would have 50% CDR to keep WotB uptime. Not sure what to do now. :lol
Nah, unless you have a Ramaladni's Gift or two lying around, you don't roll off sockets for % damage, 130% ChD eclipses 10% more weapond damage. You'll have a tough time with the Perma-Berserker without lots of CDR and the Zodiac ring, true.
I find that getting dependant on a singular buff state hurts a char. Sure, WotB boosts your stats something fierce, but without it you'll be looking at a lot of wasted base damage, affixes which could've rolled crit chance or damage instead.
However, your issues will probably be moot from today / tomorrow on, since Kanai's Cube will enable your desired build handily. You could equip the Zodiac ring's special power that way and fill something more useful into the freed slot.
Heck, complete the Wastes set so you can ditch the RorG too and go F&R, they're multiplicative with each other, so alternating between a generator and spender will buff your damage by 125%.
