Connecting the DoTs: A Summoner Guide

[Thorhall]

There is something that bothers me about the summoner and which I couldnt found in any reddit discussion or the lodestone forum. So I will post it here and am curious about your thoughts. The idea is to use piety materia (instead of our secondary stats) to gain more MP+MP Reg and therefore substitue Ruin I with Ruin III.

The calculations i did bring the following: 1 Piety equals ~ 6MP. In addition we gain 2% MP every 3 seconds which makes 0.12 MP and additional 20% every minute through aetherflow (Energy Drain is sadly not effected) which gives a total of 0.18 MP per Tick per Piety
I will go with a 7 minutes fight as example. This fight will have 140 Ticks and 1 Piety will regen about ~25MP. To exchange R3 with R1 we need additional 884 MP or to express in piety ~36 Piety. This exchange will bring us a benefit from 120 Potency or 3.33 Potency per Piety (or better 0.007 Potency per second per Piety)...

...(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.
