Kalista Visual Buff Request

Can Riot give Kalista the ability to tell when her Rend (E) is able to kill things? So many times I have missed CS, champion kills and jungle camps (as is my flavor of off-meta roles along with Vi Top and Orianna Support, don't ask me why), and it tilts me, especially during early game where Rend is on such a high cooldown. Other times it happens in teamfights where I miss a Rend kill on a champion, leaving me unable to execute any other champions effectively.

Maybe add a visual thing where the spears turn a different color indicating that the target can be killed by Rend. This would also be visible to enemy champions as they would be like "Stay away from me, that's a lot of spears" or "Contest drake, Kalista will kill drake fast w/o jungler's smite"

Plz Rito?
