from what I've seen for the first couple dungeons you can do after getting access to scholar it feels way overpowered because the damage isn't very intense and the fairy can almost do it by herself

but after that the fairies can get pretty unreliable
they just spot heal whoever is lowest, including pets, and go auto mode by themself after their first spell use
they seem to pretty often just derp out and do nothing even after giving them a command they'll fly over cast a heal then fly back to you and do nothing again
there is no way to make them focus like sic and obey just don't work for them

this is a problem since scholar heals are purposefully weaker because the fairy healing is supposed to fill in the gap
I feel it will be something worked on soon though, the pet bar needs a lot of work in general imo it has a lot of superfluous stuff that could just be remedied with auto-toggles on the individual skills and fairies need different commands altogether

Other than that scholar seems totally fine
I find it weird that at 38 my scholar has more int than mnd even wearing a few pieces of mind jewelery
the charge system i find very cool having access to what are basically supercharged spells with instant off global cooldown casts
