...(of course you can discuss the duration but i try to normalize it per second so it wouldnt be a problem as long as the fight is long enough to produce at least one substitute of R1)
Every 148 Piety we gain enough MP to substitue another R1 to R3 bringing 0.81 Potency per Piety but will have a decreasing value of Potency per second. For the 7 min example it will be something of 0.002 making piety overall to 0.009 PpS

My Problem is now to normalize this value and make it comparable to Crit/Det/SS. Maybe you can help me out.

P.S. I also don´t know if the Reg from astro, bard or machinist is flat or a percentage of our value. This might further contribute. And of course there is a hardcap when every R1 was turned into R3. This might happen espacially with reg from other classes.
