Some interesting numbers on 4.0 BLM

[Galvuu]

So much reading in this thread , but from what i've gathered - refreshing Blizz 4 in our rotations hinders our dps because it forces us to be in UI more than we have to be versus squeezing out more time in AF? Is there ever a time we want to be using Blizz 4 outside of our opener, even if the encounter allows for it? It just doesn't seem like it from what people are saying.

I should just make a new thread.
ATM you can 5xF4 without using B4. This is an unconditional pps gain, and you do this "new 3.X rotation" whenever possible.
The only reason not to is if you get a slow tick going into UI and then don't get a refund on the T3 mana. If this happens, B4 afterwards.
You end up swapping between both rotations based on mana tick timing.
