SHB BLM is the peak of this game's job design

[Archwizard]

While this might work above level 68, between that level and 50 it would mean the BLM AoE fire rotation is a single flare followed by waiting for MP. At least F2 casts give you a chance to proc thunder to get around the MP tick issue.

Considering we already avoid F2 like the plague, I would like to see the math on a rotation of F3>Flare>TP>Freeze to cap (with generous sprinklings of T2/4) vs F3>F2 till near empty>Flare>TP>T2/4.

Though I feel like if your math shows a higher PPS value on using F2 as it currently is, there might be a flaw given the concensus is to simply avoid it.
