I often see people complaining about sustain-based healing (not that I particularly mind it myself), and since grievous wounds isn't really the best idea for this sort of thing, how about an item which converts a portion of damage dealt to "grey" health that can only be recovered at the fountain or is only partially restored by healing.
Thoughts?
yeah sorry mate, but grevious wounds is designed for this purpose entirely. Since they finally added executioners calling back in any form of healing can be countered by this item as its applied on auto's which guess what all adc's and fighters use a ton of ;).
We have grievous wound against selfhealing
We have health percent damage
We have this against health stacking
We have GW to deal with selfhealing. Selfhealing isn't even a problem right now:
isn't OP because of his selfhealing. He's OP because his base armor is way to high compaired to the 
changes. This combined with the damage buffs made him go overboard.
is like any new champion that get released. Their still working on him.
still strong but far from problematic. Can even say so get close to ballanced right now
isn't problematic right now. And most issue are because of his outdated kit.
he isn't a problem
still strong but far from problematic right now
are you serious
he's fineTheir is litterly no reason to implement something like gray health when their isn't even an issue.
That is a bad idea.
What if they made an item that allowed you to corrupt units? The corruption would make it so that any healing received from that unit was nullified or did damage.
