I don't even understand why they made AC heal to begin with, to me at least it makes little sense thematically I think it'd make more sense for MNK.
They removed the damage ability from SAM when you used Third Eye which was kinda meh imo, it felt great to trigger and use it even if it was little damage.
But at least the heal was a self-heal.

RPR of all DPS having an AoE heal especially one that powerful is just bizarre to me.
