I am referencing the season 22 build. The crimson build uses band of might as well. The core build uses FnR. Because of cooldown requirements in FnR crimson will outperform initially then when proper rolls are obtained FnR will take the lead. Remember crimson can drop boon passive with suboptimal cdr for brawler or nerves of steel. Also crimson benefits from coe and ruffly 50% sheet damage from channeling pylons. It is also easy to craft any two CC pieces and slap them on. On top of this getting decent FnR rings very frustrating since crit rolls are not guaranteed like COE and Band of Might.
