Mathematical Analysis of Magicians and DoT Post-Jump

I believe you were correct the first time, unless I forgot something myself:

Without Meteo:
2788.5 + 560.0%/s DoT
= 2788.5 * 1.4 * 1.2 + 560/0.875
5324.7%/s
Using Teleport without Fire Demon or Big Bang:
2850.26%/s + 380%/s DoT
= 2850.26 * 1.4 * 1.2 + 380/0.875
5222.7%/s

And the difference should only get larger with more PDR.

I had forgotten that DoT does maximum damage.
Though infinity and elemental weapons weight in favor of not using DoT.

I'm lazy to calculate the new average multiplier for infinity, but Elemental weapons alone are not enough to make not using FD and BB worth it.
