I don't know why people complain about it.

You have a 200HP heal and a 200HP shield that's the some potency as Medica1. It has more utility and draws less enmity than White Mage's Medica. If we run into the fray and cast a Medica your best bet we will aggro something, even if it has 0 enmity on us.
Plus you have your fairy, I've seen that thing heal 700Hp. So let's do some maths if I'm almost dead, one heal from the Scholar and then the fairy is close to 1.3k HP heal, then add in the Succor and it adds 200HP and a 200shield. that's 1.9k HP in 4s.

Now look at White Mage, we have Cure which heals like 900HP give or take. the Medica which heals 450 - 600. Your Fairy makes your succor worth it. I'm yet to see a Scholar go below 50% mana in a boss fight, that's with raising people, I raise one person and I've just hindered myself for the rest of the fight unless I pop SoS. I'm just confused on why you want it buffed, I hardly ever see White Mages as it is, I have been denied a spot in a healing role because they rather a Scholar for the fairy, lol.
Out of both the class White Mage needs a slight tune to be up to par with Scholar.
