Would Riot ever allow a "steal healing" effect to be created?
Got this idea recently: What if there was some item, Champion, or whatever, who could steal a portion of an enemy Champion's self-healing? Basically, whenever the victim heals him/herself, some of it is stolen and given to the aggressor. Since it'd be self-healing only, you wouldn't be able to blame your team's Nami or Soraka for keeping your enemy alive (unless they were the one debuffed).
Would this fall under "toxic"?
