First off... Just got 82 black mage (not rushing it to 90 SUPER fast).

Already I feel they need to tone it down a bit.
Enhanced Enochian III = 20% bonus damage
Main and Mend II = 30% bonus damage (and healing? why)
3 Stacks Astral Fire = 80% bonus damage

Side note... why does Flare/Despair give astral fire for 15 seconds? Who doesn't Transpose RIGHT afterwards to Thunder III for proc'd Thundercloud or Foul/Xenoglossy (Transpose/Blizzard IV for 3 Umbral Heart for next Fire IV spam is another option).

Also...
Literally Every other Final Fantasy game...
AoE Fire = Firaga
Single Target Fire = Fire
Stronger Single Target = Fire II

Can we get Firaga / Firaga II instead of Fire II and "High Fire II"?
Also... can we get Fire through Fire IV for boost in damage over time across levels and drop "Maim and Mend" which didn't make sense in the first place?
Or maybe instead drop "Maim and Mend" and allow 5 stacks of astral fire and make damage on Astral Fire go from 40%>60%>80% do like a 20%>40%>60%>80%>100%. Also make Astral Fire stacks harder to get. A single Fire III seems too easy to get the +80% boost.
Maybe they can add something to teleport around without breaking casting cause that is the biggest issue with some bosses.

Example (and similar thing to Blizzard/Thunder):
Level 1 - Fire (Single Target)
Level 18 - Firaga (AoE)
Level 35 - Fire II (Single Target) (replaces Fire)
Level 60 - Fire III (Single Target) (replaces Fire II)
Level 65 - Firaga II (AoE) (replaces Firaga)
Level 70 - Fire IV (Single Target) (replaces Fire III)
Level 82 - Firaga II (AoE 140 potency) (replaces Firaga II)
Level 90 - Fire V (Single Target) (replaces Fire IV)
