Does anyone know of an addon that allows you to choose what debuffs you see? For example, I don't want to see all debuffs on a boss, I don't even care about all my debuffs, I have an addon for that. All I want to see is Curse of Elements, Curse of Shadows and Curse of Recklessness debuffs on my target frame. Am I asking for too much here or does anyone know of a way to track debuffs from other players that doesn't show them all?
