New Champ idea?

So I was watching Rakkan jog back to the well as we lost. Seeing this I thought: What if a champion were to be actually Immortal (like straight up can't die, at all). I mean in stats they would, but that's beside the point. What if their passive was to run back to well and regain health when they would die. Soon as they reach well they are alive and playable again. Probably should wait for health and mana to return, but still playable. The more deaths you have, the slower you walk. Like first death, run like it's nothing. Second death a jog?.......8th death limping, can barely walk. This would reward the player who survives the early game with little to no deaths. May have some issues with balancing how far to run tho. Anyways, it's an idea. not sure on abilities other than that, but ill add if I think of some that would go well.
