SS and RR caps crit dmg+ on RNG even with the increased cap (30+30+40(dead aim)=100). Therefore crit dmg+ daggers are completely useless. And yeah, any weapon with critical hit rate only applies to that weapon and nothing else.
Except you're gonna wanna use RR/GH/Sea daughter to be worth a ***on ranger. And the last thing you want on rng is a atma that gives more emnity. Or you will be face down more than you will be shooting.
I've never seen anyone use it before... and I've never really cared about bows, but that thing looks awesome! I'd say easy top 5 in looks of a weapon imo.
