Runic power returns, to the best of my knowledge are very rigid, you get x runic power for doing y and it returns z rp. Druid / priest revitalize returns can give you a bit of random rp spikes, but otherwise. And I'm more interested in this mod for a personal DPS evaluation of myself, not other dks in the group. I'd like to know if I end up hoarding a bunch of rp over the course of a fight, and find out how by how much. If i'm only wasting sub 100 rp over a 3 minute fight, not a big deal, but if I end up with 500 rp, then I need to fix my rotation up.
Would it be possible to create a mod that reports at the end of combat how much runic power a DK has wasted? Basically everytime you use a skill that returns less rp then it should (you are 120 rp, you drop a DND that should return 15, it instead returns 10 since you are capped at 130 rp) that rp would be added up under wasted rp. This number would be returned and you could see how many potentially wasted deathcoils or frost strikes you had.
