Im running the Maxroll Penshot build by Mattias, I can do tier 12 activities comfortably but play on tier 11. When doing boss fights on tier 11+ I have trouble upkeeping my cold imbuement because I cannot proc chill on bosses enough, which is the only way to reduce my cooldown via perk skills. I have some cooldown reduction affixes but i general it is quite inconsistent and im typically about 60/40 on cold upkeep. how are you guys managing it? any tips would be appreciated.
