Why the difference in duration?

I mean, WHM also has Assize for MP while AST needs to rely on rng for the mana card, and most of that time the mana card is going to be burned to provide aoe bole or arrow to the party. The only reason for a WHM to be completely out of MP and/or having MP issues is if they have to constantly keep raising party members (which is not your fault as a WHM to begin with, and also applies to AST) or if they are heavily dpsing, which they can do far better than an AST anyways. Feels balanced to me.

But AST that can put their MP back to 100% after dying (for example) by LA + Ewer + CO, while WHM can't fully regenerate MP with SoS + Assize.

Azzize: 1387 Mp (at 723 Piety), 90s cd
Shroud: 3535 Mp, 120s cd

In one minute: 2692 Mp (scales with Piety).

L. Aether: 5656 Mp, 120s cd
Ewer: 2210 Mp, 180s "cd"

In one minute: 3565 Mp

In addition to the above the AST can use CO every 2 minutes to extend their refreshes: 1326 Mp more from Ewer and and 2121 Mp from L. Aether. That's assuming they don't give the Ewer to the WMH. If they do, the AST can add an additional 2210 Mp by extending the Ewer on the WHM with Time Dilation. In total they can support another healer with 5746 Mp every 2 minutes assuming their cooldowns line up with Ewers.

Maybe its because the white mage can proc free spell ? it would makes sens that he regen less mana since he regulary have free spell.

There isn't a logic reason IMHO, they buffed the AST over and over to push away the idea that it's a bad job and increase its numbers. They'll rebalance everything out in 4.0

Freecure
Play better. If you are having mp issues it is your fault. Stop fishing for a way to blame the other guy. This is not politics.

WHMs have Assize on a separate cooldown

ASTs only other option is the ewer, which is RNG, and better saved for the royal road. You don't see an ast using the Ewer on themselves ever unless they're that starved

Using Luminiferous Aether also usually required you to use Celestial Opposition to get as much out of it as possible, but that is no longer needed, and you can use it for other things.

Are we forgetting freecure here? 15% chance doesn't sound like much at first, but considering how often you cast cure, it triggers all the time during actual gameplay.
AST procs only crit, that's all. They still cost the same amount of MP (~800 MP for me). While my WHM saves 900 MP when using Cure II with a proc.
There's Assize too, and no, Ewer is no replacement because basically an AST that needs cards for himself sucks, he's supposed to either RR it or turn it in for another card if no one else in the party needs it.

[Pingosteel]

Is that so aberrant that different jobs have different play style with both strengths and weaknesses ?

Malefic II VS Stone III ? +10 potency for stone.
20% chance free dispell , 15% free Cure II , 20% that Medica cost half MP.
5y more range for Medica II than Aspected Helios
and so on.

And I don't even talk about 4 free heals (Benediction, Asylum, azzize(+MP and dmg), Tetragrammaton) Vs 2 ( Essential Dignity, and Collective Unconscious but you can't move )

3 Healers in the game,
all 3 are powerfull and unique.
WHM got most powerfull heals (single and group), and more healing skills and burst DPS
SCH got shields, fairy with micro management, mobility tanks to Dots and great MP effiency.
AST can be replacement for both, but slightly weaker for specialty, and cards.

don't forget that Lightspeed reduces mp consumption by 25% ^^/
