ClassLoot

This addon rates each piece of loot you get and lets you know whether it is good for your current spec.

Class Loot information can be accessed in two ways, either via item tooltips or through the slash commands.

Item tooltips contain the class loot rating along with the instances the item drops in, and finally the bosses that the item drops from.

You can check the loot of any raid item by using the following slash commands:
/cl check – Personal item check (only visible to you)
/cl gcheck – Item check broadcast to Guild Chat
/cl rcheck – Item check broadcast to Raid Chat
Configuration of this addon may be performed through the Options -> Interface -> AddOns -> ClassLoot window.
