Take it or leave it, I found a thread that has some data mined info about Arcanist and Summoner. It appears Arcanists and Summoners are not healers at all but are much more like WoW Warlocks. Pet classes with DoT's and a nuke or two. No info about Scholars however. Below are alleged data-mined abilities from Arcanist and summoner...

Just translating what was untranslated in the data-mined info. I did not find any of this stuff and my translations are subject to being terrible.
Level 01 - Ruin: Deals magic damage to target. Potency: 100
Level 02 - Bio: Deals magic DoT to target. Potency: 10 Duration: 30s
Level 04 - Ruby Carbuncle: Summons "Carbuncle Mage"
Level 06 - Miasma: Deals magic DoT to target. Potency: 5 Duration: 30s Additional Effect: Inflict 20% "Heavy" & an ailment that halves the amount recovered on heals. Duration: 30s This Heavy will not be cancelled if target takes an attack. (TN: This one was tricky for me, might've @#%^ed this one up)
Level 10 - Sustain: Consume 15% of your max HP to grant HoT to your pet. Potency: 5 Duration: 15s Cannot be used if current HP is less than 15% your max HP.
Level 14 - Wither: Deals cone-shaped magic damage towards target. Range: 120 degrees
Level 15 - Diamond Carbuncle (QUEST): Summons "Carbuncle Guardian".
Level 18 - Self-Sacrifice: Out of your current HP, consume 20% of your max HP to raise your own magic damage for a set time. Duration: 12s Cannot be used if current HP is less than 20% max.
Level 22 - Miasma II: Deals magic DoT to AoE. Potency: 5 Duration: 30s Additional Effect: Inflict 20% "Heavy" & an ailment that halves the amount recovered on heals. Duration: 30s This Heavy will not be cancelled if target takes an attack. (Again, not sure of the additional effect)
Level 26 - Fog: Decrease target's range of throwing, archery, and magic by 10 yalms. Duration: 30s
Level 30 - Barrier: Raise your physical defense by 10%. Duration: 15 min.
Level 30 - Bane (QUEST): Scatter a target's DoT & Status Ailment to surroundings. Duration: Based on DoT / Ailment. If you did not inflict the DoT / Ailment there is no effect. Additional Effect: 15% chance to reset the duration of the scattered DoT / Ailment. (TN: This was a doozy. Might be way off. Sounds like it spreads an enemy's DoT or debuff to surrounding enemies. Not sure if this is the actual quest ability you learn.)
Level 34 - Bio II: Inflict magic DoT to target. Potency: 20 Duration: 60s Additional Effect: Raises target's chance of taking critical damage 3%.

Level 50 - Aura Burst: Deals magic damage to surrounding enemies. Additional Effect: Knocks back target 10 yalms. (TN: Not sure if it's the enemy you target or all hit by the spell. No potency was given in the doc I have)
Summoner Skills (These sound like Summoner abilities but I'm not sure how the levels will work out):
Level 04 - Proto Ramuh: Summon "Ramuh Spirit".
Level 15 - Proto Titan: Summon "Titan Spirit".
Level 30 - Proto Garuda: Summon "Garuda Spirit".
Level 35 - Fester: Deal damage based on the number of DoT / Ailments you have inflicted on target. "60 Potency" damage per DoT / Ailment. Only Arcanist/Summoner DoT / Ailments count toward damage. No effect if you did not inflict DoT / Ailment to target. (TN: Sorry if wording is strange. Might have messed this one up)
Level 40 - Proto Ifrit: Summon "Ifrit Spirit".
Level 45 - Harm's Way: Have your pet take damage for one other party member (excluding yourself). Duration: 12s
Level 50 - Enkindle: Execute a Fulfillment skill on currently summoned pet. Can only use when a Summoner pet is summoned. (TN: Not sure what this means without context, but maybe using stuff like "Diamond Dust" etc.?)
