I notice both discretize and snowcrows Condi Firebrand DPS builds run Grieving pieces. I'm confused as to why Ferocity helps on a condi build. Why not use sinister and get higher condi damage? Ferocity helps with crit damage but crit chance isn't even near 100% on a condi build. From watching stat sheets on DPS videos, crit chance is 69.61% with the appropriate DPS golemn buffs. Is there a trait that fills in the remaining 30% crit chance? Riteous instinct adds 25% but the build doesn't run it.
