What's the point of healing anymore?

I played a game of nasus and 4/5 enemies had ignite, 4/5 had executioners/morellos,

Then we have kat and kled giving 60% grievous wounds cause why not? Bramble vest AND thornmail both give grievous wounds.

Now healing champs get countered by tanks right off the bat, by damage champs right off the bat, and by ap champions slightly later.

But don't forget vlad is still overpowered even with all this healing reduction. Champions that abuse ravenous hunter are still overpowered. But any champion that has a minor form of sustain is screwed.

If we were to nerf ignite, remove the early and cheap to get grievous wounds, then we would see a rise in these healing champions and then we can nerf their healing accordingly instead of having champions like vlad who are balanced around having their heal be reliable through the healing reduction, so if you didn't get it you auto-lose.

TL:DR nerf or remove several forms of grievous wounds and balance champions sustain and healing around not worrying about grievous wounds
