This is my armory:
Please note that I'm using six sense passive and not determination (armory not updated).
I die really fast, my CDR is from 54% to 63% in combat - I do decent DPS (not the best..) but I die really fast I have no idea what else is missing
You have harmony on your neck and as a passive.... why?
You are using Mythic Rhythm, do you actually know how to use it or did you just see it in a build?
Why are you using Sixth Sense and not Guardians path?
Your CDR is LOW! Get more! The more time you are in SSS, the less time you are being punched/hit by mobs.
