What they should have done with fairies:

[GrimGale]

I like the concept, especially because in lore the faeries are playful like we saw in shb, though I don't think they're the same types of faeries.

I always enjoyed having to stance dance, like back when WHM had cleric stance, with monk now having fist of fire/wind/earth. If they were able to do something like you mentioned that would be pretty cool.

Though i would prefer if they remove the faerie as a pet altogether, I find it rather ridiculous having a pet cast the spells instead of the scholar. I mean I'm a freaking scholar, they read books for a living. Scholars should be able to learn how to cast these spells themselves.
Let me be able to transform into a big ass faerie, like the faerie queen lol

Scholar spell lore is rather interesting. It's almost closer to Necromancy than it is to Nature or Healing magic. The idea is that through complex geometrical patterns and symbols, Arcanists can "program" aether to create facsimiles of life. Our fairy is essentially a homunculus, an artificial life-form made out of the SCH's aether that grows as the SCH grows in power.
