Jungle Monster Range Indicator

I'm sure anyone who has played with a champion that relies on kiting monsters to jungle has had a time where they accidently kited too far and the camp quickly regained all its health back. Mid to late game this isn't such a big deal but early that mistake make all the difference. I think Riot should make some sort of indicator showing how far you can go before this happens. It would help newer (and even more experienced) jungle players not make that tilting mistake anymore. I also don't see how it would cause any harm to the game. If someone could tell me how it would, id like to know.
