I fear the kill reward shouldn't be implemented on a support item like this. It just would get abused by solo laners. If you need to secure a kill you just do it. But I don't think it's worth to nerf this item just because a solo laner abuses the sustain. I actualy think it would just be nice if it can stack. It's basicly a potion every assist.

I think we have enouge offensive items and again scaling item just doesn't work on supports. It's a defensive item for a reason. Maybe we can indeed add some more limitations to it so it won't be abused for lane sustain:


 * UNIQUE Passive: When within 1000-units of an ally champion(s) every 3th basic attack/spell on an champion you heal yourself based on the highest level from your nearby allies.

This means it won't can't charges again from hitting minions or casting abilies to minions. But it would still you a stack when black shielding an ally. This also means if you miss a skillshot you basicly get punished for it.
