By doing so I can use 4 annihilation (even 5 if Ursoc trinket active, of course Crit is needed, and if I was very unlucky, sometimes only 3)
I cannot link my wowcraft log on Normal Nythendra and Ursoc here. I currently have 51% crit and 2 relics of crit chaos, and using Demonic is really fun.
With Demon blade change in 7.1, I may try DB with Demonic.
