EDIT: Now updated for MoP Classic. Note that i’m not returning to active development of this addon. I’m only updating it (bug fixes only) while im trying out MoP Classic, and updates will stop once I stop playing again.

About
Diminish attaches icons to unit frames or nameplates, displaying time left until a crowd control diminishing returns category expires for that unit. As well as how far the category is diminished. (Green border = 50% duration, yellow = 25%, red = 0%)

DR icons for each unit frame is separately configurable. Certain unit frames are default disabled for tracking or only enabled for certain zones.

Also optionally tracks DRs for NPCs. Normal mobs shows stun/taunt DR while special mobs shows all categories.

Configuration

Type /diminish to open the options panel. You may also skin the icons using Masque.

You can manually set static icons used for a DR category by right clicking one of the checkboxes under "Enabled Categories" section.
