Connecting the DoTs: A Summoner Guide

DWT > Fester at 1 GCD in. Fester + Deathflare on the last Ruin II.

Well that's only really doable with the 2P1F opener as opposed to the 1P2F as Fester will be cooldown when you Trance, unless you Painflare last but by then your DOT's would start falling off before you can Tri-Diaster in Trance.

The opener aside I'm not sure about using Painflare in one Aetherflow cycle just so that you can Fester twice during Trance with 10% Magic increase.
Do the two 10% Festers even make up the 100 potency loss by using Painflare over Fester?

Nope, which is why that opener is a DPS loss, unless it causes the dot timers to line up better with phase jumps.

The only time you painflare (in a perfect single target situation) is during your opener. I use Sleighs opener, the reason her opener is so effective is it maximizes the use of your potion and litany/trick attack. After the opener, you use two fester and Tri-Disaster, during DWT. Then after around 20 secs you use fester again. So every time you use DWT you have 3 aether stacks for the two Festers and Tri-Disaster.

I think you might be misunderstanding what Kona first stated.

If you are using Sleigh or my Opening, the first DreadWyrm Trance, you will only be able to Fester once inside it.
However, the DreadWyrm Trance in the rest of the encounter you want to line up with Aetherflow usage. So essentially what will happen is you will wait to use your last AF stack still the Aetherflow CD is less then 30 seconds (preferably closer to 20 second remaining) and then you use your last stack. This then leaves you with three Aetherail Stacks and zero Aetherflow stacks. However the timer of Aetherail stacks will be 30 seconds, but the CD to get Aetherflow Stacks back will be less than 30 seconds.

So when Aetherflow finally comes off CD, you will wind up doing something like:

Some skill / Ruin II -> Aetherflow -> (Some skill/ Ruin II/ No skill) DWT -> Fester -> Ruin III Spam, Tri-Disaster + Contagion somewhere in between -> Ruin II -> Fester -> Deathflare.

This is true regardless of what opener you use.
