I don't like some of those abilities, too similar to some Thief abilities and one is clearly Enmity Douse 2.0.

I've mentioned such an idea before, but I didn't really give it much thought until (I think) Rambus likened Scholar to Corsair. Basically, give Scholar some buffs that are based off enmity.
If Corsair has a buff that gives you Refresh, the best when it rolls a 5 (or 11), think of something similar for Scholar that gives the best bonus when the targets enmity level is at 50% according to Libra.
The idea clearly needs fleshing out, but it's the only real way I can see Scholar working with its Enmity roll. I don't even think it should be given any ability to control enmity outside maybe a "Enmity stays as it is for x amount of time", I'd much rather see Scholar have to tell a Thief to take some of a Monks enmity so the Monk can deal better damage, it seems far more like the roll of a General that I think Scholar is meant to fill. Other jobs would need more ways to control enmity in that case. Dragoon and Black Mage already have enmity wipes I guess (I want their buff to require 50% enmity just to trollface.jpg).
