I totally support that using wrath and dropping our heal buff should provide a benefit in terms of survivability. even in a WP speedrun, I'd rather provide breathing room for the Healer to cast Holy.
I think SC should have a shield benefit, that would give us more flexibility on how we mitigate damage on single vs multiple target. A High potency skill is not what WAR should be using wrath for. Plus we already have Unchained for extra damage.

Another option that could be interesting would be an AoE repel option with a short bind. It would give us some air and would fit the animation of the skill.
