The more I run Savage, Titan especially, the more I wonder why they didn't give WHM an emergency aoe shield aside from wings.
And that's not me saying wings is weak, but the second we don't have mitigation from another healer or tank we all just die even if at full HP, and it sucks so bad that there's nothing we can do about this.
In a pinch, AST does have two sources of aoe mitigation. Collective and Neutral Sect. I'm not saying WHM needs to turn towards big mitigation, but they said themselves that they wanted to close the gap between pure healers and shield healers. All it seems like to me is the shield healers got more heals and the pure healers got tossed a bone.
