One can always dream- FFXIV Black Mage edition

Just what if these changes were to happen... 

Black Mage

- Fire IV and Blizzard IV both change as follows:

- Fire IV and Blizzard IV no longer requries Enochian

- Fire IV and Blizzard IV base potency nerfed to 250

Enochian is entirely revamped: heals HP of self + freezes the current timer of Astral Fire or Umbral Ice for 5 seconds + transfers agro on self to whoever the monster is attacking at the moment; the Astral Fire/Umbral Ice clock freeze effect ends after 5 seconds or if a Spell is used (notice that Abilities are not included) (the clock would restart ticking when the spell finishes casting); additionally, cooldown reduced to 30s

Blizzard IV changes as follows:

No longer refreshes Enochian

Deals AoE damage with reduced potency depending on the number of targets, like Flare or Holy

Costs 0 mana with at least one Umbral Ice

Cast time reduced to 0s when MP is below 50% (still subject to GCD- think Ruin II)

When used under at least one Umbral Ice, immediately grants 3 Umbral Ice stacks

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!)
