Should WHM get a personal damage buff?

[HyperiusUltima]

Unless this would throw the balance out of whack: I think they should add a shielding property to Asylum.
Have a damage reduction of 10-20% or something whilst inside the shield as well as the heal - extend the cooldown if needed.

That’s actually not bad. It’s already on a 90s CD isn’t it? You’d be trying to homogenize the Healers that way though and it doesn’t necessarily make WHM better aside from finally being some type of utility that’s Raid-wide.
