All of the above plus, on top of Shadow Flare, toss in a Maisma II where you can and don't forget to use Rouse for Eos.. that extra +40% healing from her should make it easy to have everything under control.

It's helpful to have all 3 stacks of Aetherflow up and ready as well as Aethflow off of CD and ready to replenish, 6 Lustrates go a long way. Stoneskin is also something that will make life easier though it's a longish grind to get, but negating 10% of the tanks max hp in damage is a very nice thing to have on hand especially in the case of a WAR with high HP.

WHM's have nice big raw heal bombs but your bubbles, Eos and stoneskin (when you get it), along with Shadow Flare, Maisma II and Eye For An Eye will negate much damage and retard mobs to a point that SCH healing/mitigation is terribly potent and, speed runs are quite easy after some practice (and the right group that is attentive and works together).
