Bring back the range indicator on Nunu's W

When Nunu was released he had an indicator on the minimap that showed how far he could reach with his snowball. It was really helpful to know when to use it so that it would be big, but not expired, by the time you got to where you wanted to throw it. I've heard some people say that it wasn't accurate, but it seemed close enough to me to be very helpful.

A while back they took this away, undocumented. I don't know why for sure, but I hope they bring it back sometime soon.
