New DRK is awful. Here’s why and what could be done about it.

PLD numbers on that spreadsheet seem incredibly bogus. 50% boost only applies when MP is +80%, which it won't be after 3 holy spirits. So Confiteor will never be 1200 potency unless using it within those 3 opening spells under Req.

The bonus applies if your MP is above 80% when you use requiescat, not during the buff.
