Rare and Legendary Item Usage Stats
Class: Witch Doctor

I read the top 5000 10000 DPS characters of each class (in Americas region) from DiabloProgress and then loaded their items from the D3 public API to see what kinds of items well-geared players of all classes are using.

Here are the results, sorted from most common to least common usage of rares. The table on the left is percentages of rares and leg./sets of that item type within the item slot, and the table on the right is percentages within the specific item type.
