We need a Grievous Wounds item for ADs/Tanks

With the removal of Executioner's Calling, a lot of high-healing AD champions have become rather difficult to handle, for example a Yi with Bloodthirster and BotRK will happily shred through enemy teams one by one and heal himself up in the process (And don't forget the W). Or Fiora, or Zed (sometimes), or even Mundo (but maybe less shredding.) So either we bring something like Executioner's Calling back as an item that actually makes sense to be bought with meaningful stats or we give tanks the opportunity to apply Grievous Wounds onto the enemies to add a bit of utility with some sort of MR/AR item.

EDIT 1: I seem to have been talking out of my rear-end for this one. Apologies. It's true that EC was never bought as, despite GW being a useful thing, it wasn't very cost efficient and the stats were not quite good enough. The removal of EC doesn't seem to have affected the game for the most part as not bought is still not bought now. Nonetheless, I would like to see an item that applies GW for ADs or tanks simply because some champions are able to stack up lifesteal and use this stat to their advantage either in the form of Fiora's ult or a Yi's sheer unstoppableness. Let's say I play Thresh, I hook a Fiora and she takes so much damage that she's down to 20% HP. In the split second during which I cannot apply any more CC to her for whatever reason, she presses R and is easily back to 80% HP if she has around two lifesteal items. Same with Yi. With his Attack Speed, true damage and his Q to boot, he's awfully hard to keep down unless he is feeling brave enough to run into a fight even he can't win, supposedly a 2v5 or so. I'm just saying. I've seen champions heal themselves up from 10 to 100% of their HP with a mere three auto attacks after a fight. Should I have died, my team would have no possibility to finish the job at all.
