You have a good point with Healing Rite, but Healing Rite to me is an item that gives a lot more options than what I'm suggesting here. For example, Healing Rite is still very useful in the late game if you want to heal 400 health quickly to hover over a possible team fight instead of basing or generally in the early/mid game you can use healing rite and to clear camps with the effect active during it, because the effect is not interrupted by NPCs so almost every hero can clear 1/2 camps and then return to the lane without losing much health.
With this item I would like to offer an alternative to healing rite, something that is better than healing rite against poke heroes like Talon/Pocket/Paradox but not really viable against other heroes during the lane phase.
An example of why I would want such an item in the game: Currently in high elo lobbies there are players who are very good at paradox, they poke you low and deny you a lot of souls, without any real counter play. Without help they most of the time expand that lead into a early tower/kills, roam to other lanes or sometimes even take early walkers. Right now there is no good item that helps against it except healing rite and that doesn't really help either, I would like to farm as well as possible in such a lane and give up my kill preassure just to hold the tower and don't fall to far behind.
