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!)

Announcing New Final Fantasy XIV Patch Notes
I have noticed a pattern of content in 2.0, and I felt it was a important enough subject to share my view on what I hope is not a repeat of what could be described as "Cookie Cutter" Patch notes in 3.0.

Final Fantasy XIV to lack challenge?
Having said that though, I'd wager that figuring out something that they may not care about much or have the patience for isn't a good enough means for a challenge

ff14gilhub:What Class, City-State, and Grand Company to Choose in Final Fantasy XIV
The thing is though, narrative wise your character actually is not from that nation or even Eorzea period - canonically they're a 'foreigner' from somewhere else in Hydaelyn who has made the journey to Eorzea to take up work as an adventurer inspired.

The Final Fantasy XIV spam needs to stop
Bots started to show up everywhere, every NM was being camped by gil sellers, they even began to challenge legit HNM LS's at camps...Mobs like tiamaat for example.

You need to get used to doing your ffxiv tank CDs
That's covers the most important aspect of your questions (you absolutely can't endgame tank without understanding provoke and swaps)

I also have no idea if this is the final build for Au'Ra ffxiv character models
I also have no idea if this is the Final Fantasy XIV build for Au'Ra character models and/or if they are gonna get ffxiv gil revamped slightly.
