However, Heal might gain a purely passive component to slightly benefit the person that picked it.
What if heal had: The one mastery we are adding specifically gold related in Utility is a mastery called "Pickpocket" that grants gold upon attacking an enemy champion. This will allow active supports a bit more gold while harassing their opponents, while also being useful for other character types that spec into deep into Utility.
That as a passive. Or one of those summer spell based passive. If its a health/regen or something ad carries would probably still be picking it up over barrier.
