Scholar is extremely powerful in endgame. Both titan, which can hardly be considered endgame anymore (its quite possible to solo heal titan as sch if you manage your pet, which you should, cus you should. No other class has abilities auto used, and neither should a sch) and coil allow sch to shine.

Coil 1: Probably the easiest set up for this fight is dual scholar. Makes the fight pretty snooze.
Coil 2: Sch + WHM really shines.
Coil 3: lulz
Coil 4: any time a tank is getting wrecked, you want a sch.
Coil 5: idk, my bff jill.

The ONLY thing wrong with current sch: the fact that using an ability takes the pet off steady. While its possible to work around this, it wastes time, which is no good. This too, however, can be dealt with by good fairy placement (in which case you never need to manually embrace, so then its just managing the aoe).
