Kalista Rend display

Currently Kalista's E - Rend can be hard for unfamiliar players to guestimate how much damage will do, especially since the number of spears past a certain point becomes unclear as the spears stack over each other . I feel like a good quality of life change would be to make it so that the amount of damage the speared enemy will take is clear. I thought a good solution might be to make a line appear on the right side of the enemies current health, that moves down as more spears stack to indicate how much damage will be done. This would be sort of similar to Pyke or Urgot's ultimate execution thresholds appearing on the enemies health bar, but changing and from the right side of the bar. I can't see how this would negatively impact experienced Kalista players who already know how much damage the Rend will do.
