White Mage (WHM)
Ah my first healer crush and also my go to healer before leveling both SCH & AST.
A reactive healer with very strong group and single target healer.
Its pretty much you lose hp, I will heal you up kind of class.
No issues with mana if you know how to manage your heals properly.
Also has many spells that regain mana or stop mana from being used.
A free instant cast shield every 30 seconds and free instant cast heal every 60 seconds is godlike powerful.
Out of the 3 healers WHM currently is the strongest healer in my own opinion.
Fun factor probably the least as i dont find it very challenging to play and very beginner friendly however it is not easy to master at the same time.
Also lilies mechanic is kind meh and can use some rework to be more interesting than what it is currently.
Scholar (SCH)
Another strong healer capable of putting out shields to mitigate damage, while doing other things like healing or dealing damage and a reliable healing fairy pet.
Being a SCH was an awesome experience due to the fact that when you or the party takes light damage, my pet can take care of the healing while I continue dealing damage. Waiting for that moment when my fairy cries for assistance then il become a true healer. In my case, my pet is the boss who tells me when to heal or shield.
In my opinion, it is in scholar's best interest to understand mechanics of boss fights as this will make your shielding life easier as you know when the next big attack is coming so you can start pre-shield the tank or your party.
Scholar in my opinion is more fun than white mage due to management of aetherflow stacks, deploying shields at critical moment and becomes a dps when no hp is loss.
Basically a 2 in 1 package role. Literally my go to healer when i secretly want short que as a DPS than can heal.
Mana management is not an issue for scholars as they can rely on free heals from aetherflow mechanic however they do need to pay a little attention at times when all 3 stacks are depleted and aetherflow is on cooldown. Anyway, having a pet fairy with infinite mana throwing out heals is pretty awesome.
Astrologian (AST)
My last healer and my biggest regret is to not learn AST first.
Although it was quite boring to start with but as you unlock the draw system, minor arcana and sleeve draw i must say i am having a blast with this healer.
Another unique feature about AST is by having 2 stances, which turns you into a mini white mage or mini scholar. So now you can place regen or shields and play yugioh / magic the gathering cards at the same.
To me, AST is literally a jack of all trades / utility healer who can fill most roles and most of time relying on heart of the cards for good draws to buff your party.
Mana management is pretty good. The Ewer mana regen is not overpowered and Celestial opposition extends Lucid dreaming which is sooo good.
I will until the day when Astrologians start wearing duel disks.
All in all, i love all 3 healers and their unique play style
However if i have to rank them from my favorite in order it will be : AST > SCH > WHM
Let me know which are you current favorite healer im looking forward to read everyone's comments.
