A nerf that should never have happened.

"Essence Reaver Now reads "UNIQUE Passive: Gain increasingly more Cooldown Reduction from Critical Strike Chance provided by other sources (maximum +20% additional Cooldown Reduction at 30% Critical Strike Chance)" from "UNIQUE Passive: Gain up to +20% additional Cooldown Reduction equal to your Critical Strike Chance from other sources."

Nerf should never have happened because they should never have listened to someone who said to give ONE ITEM 30% cdr in the first place.
