WHM and AST have a dichotomy - both have a casted AOE filler spell. WHM's is centered on the WHM, AST's is centered on a given target.
SCH and SGE do not - both of them have a spell that is point blank AOE centered on the caster, that is also instant cast. For those keeping score, they ALSO have the same MP cost (400) and nearly identical Potencies (180 for SCH, 170 for SGE)
ONE OF THEM should probably be a ranged spell.
The reason I say Art of War over Dyskrasia is that SGE is already designed for near-melee range combat. Plgema requires it (6y range), and Pneuma somewhat does (aiming its line AOE through the enemy pack and not being at the end of its range before it hits all enemies), as well as Kerachole being centered on the SGE meaning the SGE needs to be somewhat near the center of the party.
Contrast SCH, which has no other melee range abilities, and unlike SGE, can use Sacred Soil at range as well as any Eos based abilities by using Place with Eos and sending her into the melee on your behalf.
I suppose it doesn't matter which one, but Art is the more logical choice. Give it the old Tri-Disaster little "pew pew pew" lasers that hit an enemy and then make the Art of War 2 ground animation = profit.
.
This is a pretty simple suggestion, so I'm curious what the pros/cons are and if anyone would oppose this thing that would make SCH and SGE less same-y or if people kind of like the idea.

Comparison of Healer spam AOEs: All cost 400 MP and all have a 2.5 sec recast
WHM - Holy 3: 2.5 sec cast, 150 Potency + Stun (4, 2, 1 sec), 0y Range, 8y Radius
AST - Gravity 2: 1.5 sec cast, 130 Potency, 25y Range (targets specific enemy), 5y Radius
SCH - Art of War 2: Instant, 180 Potency, 0y Range, 5y Radius
SGE - Dyskrasia 2: Instant, 170 Potency, 0y Range, 5y Radius, procs Kardia
Note how the latter two of these are effectively identical while the first two, while doing basically the same thing, have clear distinctions between them in the form of cast time, secondary effect (Holy's Stun), range, and radius.

EDIT:
An alternative suggestion from Nizzi that I kinda like:
Remove Art of War and make Ruin 2 into Ruin 4 (though with lower potency than the SMN version, obviously, and with no CD or anything)?
Meh, I'm down. Sure, let's just do that.
