Let's say we're at a fancy party. Everyone has a nice huge steak on their plates. The host, GameDevDesigner, comes by to pour the drinks. While he's pouring Astrolina and Scholario's water, he leans in and whispers "Hey, I'm pretty hungry. Could I have about 20-30% of that steak? In return, you'll get a salad, dessert, mixed drinks, a gift basket to take home, and a valet to take care of your car."

Whitemagos says, "Uh. You guys have a lot of stuff there."

The other two screech "BuT YOuR StEAk IS BiGgeR SO ItS fAIR"

The above party is the history of the healing role.
