A different problem with smartcast range indicators...They're too short.
's Quickdraw,
's Sentinel,
and other "line" abilities with variable range display their minimum range when the spell icon is moused over.
This is a problem because it is impossible to tell how far the spell can go, which makes it difficult to measure whether dashes and skillshots will make it across walls. It took me a week to figure out why Sentinel was not automatically traveling the distance I saw in the Champion Spotlight.
The alternative would be like
's Crescent Strike. The indicator displays max range by default, which helps to determine whether you can connect for the rest of her combo.
Other abilities affected:
's Undertow
's Spinning Slash
's Vault Breaker (non-issue since indicator displays during channel)
