Zac's Slingshot Range Indicator

I play Zac a decent amount, and one thing that's always struck me as annoying was his E's range indicator. At first, the gripe was that hovering over his E would only show the range of the slingshot in the direction he was facing; I thought it'd be very helpful having a circular display around him, because trying to figure out if I could make it somewhere behind me while I'm running from someone, or trying to get the right angle on a gank is much harder if it's not within that indicator range.

Recently I noticed that it doesn't even show the max range anymore until you actually cast it; it's just the base minimum around Zac until you hold it down to charge it. Now it's even harder to gauge your range anywhere, and I often find myself underestimating or overestimating how much I can jump at a given time. At the very least, Riot, is it possible to revert it? It'd be great if you could consider a full circular indicator, too.
