I find decursives live display list useful. I disable the rest of the addon. Basically live list is useful because it displays every debuff in the whole party in a way that is easy to read and know immediately if it is a problem (i.e. debuff name text and magic/poison/disease in colored TEXT). There is just too many various debuff icons to know what each one does without hovering mouse over it. Text is good.
