Idea for Spirit visage and GW
What if Spirit Visage decreased Grievous wounds by like 10-20%? Similar to how Randuin's decreases crit damage. This'd allow some wiggle room for champions like mundo, vlad, and swain with the new Executioner's calling coming in. You'd still be reducing their healing by 20-30% each time you damage them, but this way they stand a fighting chance.
