Twintania in a nutshell

[Yenn]

Pretty sure you're the only guild in the world seeing this Fireball bug (or at least only one with any consistency?), and Summoner burst is fine on Conflag if you position them under the boss for Bane + Fester.

Fireball timer literally happens ~2 seconds before Waxen duration is out, and impacts right as it goes away (Unless you're standing directly under the mob, maybe? I don't know). We have never, ever experienced it "Refreshing" stacks or anything. Perhaps its hitting pets and you are mistaking it for a refresh or something?

I posted it in the bug section and it was accepted. I also linked a video of it (but the FC didn't intend for that video to be public).
With that said, killing 4 stack Conflags with SMN really cuts it close, even when it doesn't bug. Bane + Fester doesn't really provide enough damage and Aetherdam cooldown is so long that one of the Conflags won't have a stack up to use Fester.

We're resorting to the same strategy as you (or maybe not, I don't remember which group is using it), which imo is really stupid and definitely isn't intended.

If you preserve a 3stack from phase 1, you can always have at minimum a 1stack + aether (so you can bane - aether - fester).

I didn't think of using Aetherdam at 1 stack. That would probably work.

Just saving a 3 stack from P1, I Bane + Fester to 1 stack, then on the next Conflag Bane + Aether + Fester, then use my remaining Bane + Fester on the third, but I don't get my next Aetherdam until the middle of the fourth, at which point I've wasted 50% of the Conflag duration getting DoTs up.

Aether is 1min CD, and conflag is a 30 second CD (which means at worst it is going to line up with Aether CD, at best its going to be a few seconds behind Aether CD)

3 Stacks -- Conflag 1 Bane - Fester
1 Stack -- Conflag 2 Bane - Aether - Fester
2 Stacks -- Conflag 3 Bane - Fester
0 Stacks - Conflag 4 Aether - Bane - Fester
