Scholar is painful to play in under 30 dungeons because you're basically just a bad DPS with a healing turret before you get adlo. They're also the only healer that doesn't get a plain aoe heal at level 10, succor unlocks at 35. Eos can aoe heal but it's a party-wide regen and has a 60s cooldown. I've gotten tanks in Aurum Vale before who'd become frustrated with me for not using whispering dawn in the first pull room because "i want a regen" and I'm just "i want to live".
