Self or ally targeted heals becone enemy targeted damaging spells, so I think Dr. Mundo would deal 60% max HP damage over 12 seconds to an enemy and slow them for 35% for the duration.

Nasus' ult would be so good, heal allies for 5% of their max HP per second for 15 seconds :D Also, would it shrink him?
