One can always dream- BLM edition

[Il_Gatto_Nero]

Motivation for simplification: while one can always "git gud" and thoroughly study the fight to minimize movement, with a gazillion things going on at once for the very difficult fights, it can be all too easy to lose track of one (or more!) of the timers.
Also, when the boss cannot be attacked, losing even one of the timers can be a pain.

Fire IV not adding Astral Fire means that you still have to be intelligent about deciding Fire IV vs Fire I (4-4-1-4-4 vs 4-1-4-4-1 vs 4-1-4-1 vs...) - a step up from blind Fire I spam while occasionally minding the Firestarter as in 2.x.
As for Enochian itself- how about revamping it completely; I added something in the original post.

The proposed change to Blizzard IV would allow you to do something like this:
Fire III -> Fire II a few times -> Flare -> Transpose -> Blizzard IV (deals AoE damage + 0s cast time + 0 mana cost- even if the tick is fast enough, one mana tick on one stack of Umbral Ice still fills you for below 50%) -> rinse and repeat from Fire III (now on reduced recast due to the changed Blizzard IV giving you three Umbral Ice stacks!)
